J1000 REPAIR MANUAL Section 2 THEORY OF OPERATION

2.1 INTRODUCTION The theory of operation for the J1000 AM broadcast transmitter is presented in this section. Unique circuits are explained. Electrical schematics, referenced throughout the text by an SD-#, are located in Section 6. 2.2 TRANSMITTER OVERVIEW The transmitter operates at one fixed frequency between 530 kHz and 1,610 kHz and provides up to 1,100 W of RF output power. It may be operated locally when co-located with the studio, or remotely when the studio is at a different site. The transmitter circuitry is subdivided into four functional blocks - exciter stage, ac/RF power stage, RF combiner/output filter stage and control/ monitor stage (see Figure 2-1). 2.3 EXCITER STAGE The exciter stage contains two exciter sections (A and B) that can be selected automatically or by local or remote control. Each exciter generates its own RF frequency source, PDM, and digital control signals for use in the RF power stage. The exciter stage consists of exciter interface PWB (1A3), RF synthesizer PWBs A (1A4) and B (1A6, if installed), interphase PDM driver PWBs A (1A5) and B (1A7, if installed), power supply assembly (1A8) and LVPS buck converter PWB (1A9). See Figure SD-2.

2.3.1 Exciter Interface PWB The exciter interface PWB (1A3) provides signal distribution and interconnection for power supply assemblies A and B, RF synthesizer PWBs, and interphase PDM driver PWBs (see Figure SD-11). 2.3.1.1 Exciter Selection The selection of regulated voltages, carrier frequency signals, and PDM signals depends on the position of relays K1 and K2. Relays K1 and K2 remain in their de-energized state until a +5 V Changeover Relay Control signal is applied to the gate of FET Q2. The ±15 V and ±5 V sources are applied to RF synthesizer PWB (A) and interphase PDM driver PWB (A). The PDM for the RF power stages is sourced from interphase driver PWB (A). When a +5 V Changeover Relay Control signal is present, relays K1 and K2 switch to their energized state enabling the B exciter circuits. 2.3.1.2 RF Drive Monitor The RF drive (C) signal applied by the active exciter is monitored by transistor Q7. If the C signal is not present, transistor Q7 turns off and an RF Osc Fail signal is applied to the control/monitor function. This will initiate an exciter changeover or transmitter shutback. 2.3.2 RF Synthesizer PWBs The RF synthesizer PWBs (1A4 and, if installed, 1A6) use direct digital synthesis (DDS) to generate carrier frequencies within the AM broadcast band (535 kHz to 1,610 kHz). The output of a digital synthesizer integrated circuit with internal high-speed 12-bit digital-to-analog converter is low-pass filtered to provide a sinusoidal continuous output. The sine wave is digitized and divided by a factor of four to obtain the carrier frequency. The digitized sine wave is also divided by a factor of N to obtain a 2PDM frequency that ultimately determines the transmitter's pulse duration modulation (PDM) frequency. The RF synthesizer PWB consists of a microprocessor, direct digital synthesizer, low pass filter, digitizer, balanced drive, and N divider. See Figures SD-12 and SD-13. 2.3.2.1 Microprocessor The microprocessor consists of an 87C51 integrated circuit (U4), which is clocked at the system oscillator frequency (10.0000 MHz). Firmware resides in U4's internal four kilobytes of EPROM memory. The microprocessor generates control information for the DDS circuit, generates control information for the N divider circuit, and provides the appropriate sequence and control signals to all power modules during transmitter tuning, where required by the host transmitter. 2.3.2.1.1 DDS Control Information The RF carrier frequency is set using five binary coded decimal (BCD) switches (S1 through S5). When a current-sink-to-ground is applied at the Reset DDS input, or during turn on, the microprocessor monitors these switches and outputs the appropriate 48-bit value to the DDS Frequency Tuning Word #1 register. The 48-bit value is written in six consecutive bytes to the DDS's six internal registers. The sclk signal is enabled on each write cycle.


2.3.2.1.2 N Divider Control Information The 4C/B frequency is divided by an 'N' factor to provide 2PDM output frequency between 126 kHz and 134 kHz (when E3 is set in LOW PDM mode) or between 245 kHz and 276 kHz (when E3 is set in HIGH PDM mode) (see formula below). The microprocessor determines the value of N and outputs the information at pins 2, 3, 4, 5, 6 and 7. The N divider circuit uses this information as the N dividing factor. J1000 transmitters use the HIGH PDM mode. - for PDM = 130 kHz (HIGH PDM position):

C and PDM are expressed in kHz

2.3.2.1.3 RF Drive Tuning Control U4 is a microprocessor integrated circuit which monitors the status of control signals provided by the transmitter, where required. It also provides control outputs that enable the RF drive tuning circuits and inhibit the pulse duration modulation (PDM) while the RF drive tuning is enabled. These inputs/ outputs are not applicable to J1000 transmitters. 2.3.2.2 Direct Digital Synthesizer The direct digital synthesizer consists of integrated circuit U5 (AD98525Q) and associated components. It generates a frequency of 4C based on information provided by microprocessor U4 (refer to paragraph 2.3.2.1). Integrated circuit U5 is a CMOS, numerically controlled oscillator with a 48-bit phase accumulator and 12-bit digital-to-analog converter (DAC). The phase accumulator, which is responsible for generating an output frequency, is presented with a 48-bit value from the Frequency Tuning Word 1 registers, whose contents determine the FTW as follows: The 10 MHz clock input is coupled with U5's internal programmable reference clock multiplier. This results in a system clock of 50 MHz (i.e., SYSCLK = 50 MHz). The 12-bit output from the phase accumulator is input to the DAC, which outputs a stepped sine wave at a frequency of 4c. The 4c output is then low-pass filtered to remove high frequency components. 2.3.2.3 Low Pass Filter A low-pass filter consisting of C21, L1, and C23 removes the high frequency images present in the DDS output signal. The output is a sine wave at a frequency of 4C. 2.3.2.4 Digitizer The output of the low-pass filter is connected to a digitizer circuit consisting of transistor Q4, inverter U10:B, and associated components. Inverter U10:B outputs an approximate square wave at a frequency of 4C, which is applied to a 4 circuit and to the N divider circuit.

2.3.2.5 Waveform Symmetry RF DRIVE SYMMETRY potentiometer R32 is adjusted for an RF drive output waveform, which is a symmetrical square wave (50% duty cycle), as measured at the input to the balanced drive circuit (TP6). The position of SYMMETRY ADJ shorting jumper E6 determines when the RF drive symmetry circuit is enabled or disabled. E6 should be installed in the ENABLE position (shorting pins 1 and 2) when used in an AM broadcast transmitter. 2.3.2.6 Balanced Drive The balanced drive buffer is a switching circuit that ensures the rise and fall times of its output square wave are minimal. The C signal is a 15 V peak-to-peak square wave that is the low level RF drive signal for the RF power stage of the transmitter. 2.3.2.6.1 Balanced Drive Matching Shorting shunt post E5 is installed on seven-position header XE5 to choose the optimum capacitor and resistor values. It is installed in the D position (shorting pins 7 and 8) for J1000 transmitters. 2.3.2.7 N Divider The N divider circuit is a cascade counter made up of integrated circuits U6, U7, and inverters U8:A and U8:F. The 4C/B signal is divided by N to provide a 2PDM frequency, which is between 126 kHz and 134 kHz (when E3 is set in LOW PDM mode) or between 245 kHz and 276 kHz (when E3 is set in HIGH PDM mode). The value of N is supplied by microprocessor U4 (refer to paragraph 2.3.2.1.2). The 2PDM output, which is nominal 5 V peak-to-peak pulses, is applied to the transmitter's pulse duration modulation (PDM) generation circuit, and ultimately determines the PDM frequency. 2.3.2.8 RF Drive Source Selection The RF drive source may be provided by the integral numerically controlled oscillator, an external RF generator at c, or a 10 MHz reference. The position of shorting shunt posts E1, E2 and E4 determine which RF drive source is selected. 2.3.2.8.1 Internal c Source When the integral numerically controlled oscillator’s output is used as the RF drive source, the shorting shunt posts must be configured as follows: E1 in INT position (pins 2 and 3 shorted) E2 in INT position (pins 2 and 3 shorted) E4 in INT position (pins 2 and 3 shorted) 2.3.2.8.2 External c Source When an externally generated carrier frequency is used as the RF drive source, the shorting shunt posts are configured as follows: E1 in INT position (pins 2 and 3 shorted) E2 in INT position (pins 2 and 3 shorted) E4 in EXT position (pins 1 and 2 shorted) The applied RF must be precisely the carrier frequency (c) and its peak-to-peak voltage (sine or square wave) must be more than 5.0 V but less than 12.0 V.


2.3.2.8.3 External 10 MHz Source When an external 10 MHz signal is used as the RF drive source, the shorting shunt posts are configured as follows: E1 in EXT position (pins 1 and 2 shorted) E2 in EXT position (pins 1 and 2 shorted) E4 in INT position (pins 2 and 3 shorted) Cables are provided in the transmitter’s ancillary kit to connect between J7 (and J8, for dual exciters) of the remote interface PWB and J2 of the RF synthesizer PWB(s). The applied RF must be precisely 10.00 MHz and its peak-to-peak voltage (sine or square wave) must be more than 2.2 V but less than 8.0 V. 2.3.3 Interphase PDM Driver PWBs The interphase PDM driver PWBs (1A5 and 1A7) produces two pulse trains of variable width as its PDM (PDM 1 and PDM 2) outputs. Each pulse train contains the same data but are offset from each other by one-half their repetition rate. The PDM repetition rate (PDM) is a fixed frequency normally between 128 kHz and 140 kHz. The frequency is determined by the 2PDM input, which is a derivative of the carrier frequency. These PDM drive signals determine the transmitter output power level, as well as the output modulation level, when applied to the modulator assemblies in RF power modules A and B (see Figure SD-14). 2.3.3.1 Carrier Level Control The carrier level control circuit consists of U6, U2A, U2D, U3B, U3D, and their associated components. U6 is a four-quadrant analog multiplier connected as a variable gain, wide-band, linear amplifier. The modulation reference (I1) input is multiplied by a factor determined by the level of the carrier ref (I2) and B+ ref (I4) inputs to determine the gain and, in turn, the I3 output. 2.3.3.1.1 When there is no unbalanced audio input at J1-15, U2D's output (TP6), which is the modulation reference, will be a nominal 1.4 V. When a pure audio sine wave is present at a level that will produce 100% modulation, the output of U2D will be a sine wave varying from 0 V to 3.9 V. The resulting current flow through R12 is U6's I1 input. 2.3.3.1.2 The carrier ref input at J1-2 is a dc voltage directly proportional to the expected RF carrier level squared. When the expected carrier level is the transmitter's rated carrier level, the carrier ref input and the output of buffer U2A (TP5) are a nominal 4.7 V. The resulting current flow through R13 is U6's I2 input. 2.3.3.1.3 The B+ ref (1) input at J1-3 is a dc voltage directly proportional to the B+ voltage being applied to the transmitter's RF power stage. When the B+ voltage is 350 V (for high power operation), the B+ ref (1) input and, in turn, the output of buffer U3D (TP3), are a nominal 6.1 V. The resulting current flow through R20 is U6's I4 input.


2.3.3.1.4 The gain of U6 and, in turn, the current flowing from its I3 output, is determined by the following formula:

When the carrier ref input (I2) is 4.7 V (transmitter's rated carrier level) and the B+ ref (1) input (I4) is 6.1 V (B+ voltage of 350V), the gain of U6 is 0.76 for the modulating reference applied to I1. U6's I3 output current is 0.76 times its I1 input current. U3B is connected as a less than unity amplifier and its gain is summed with U6's gain. The end result is the total voltage gain of the circuit, relative to the voltage at the output of U2D (1.4 V when no audio is present), is a nominal 0.67 when GAIN TRIM potentiometer R31 is set to the centre of its range. When there is no modulation present, the carrier ref + audio output of U3B (TP8) is 0.94 V (1.4 V x 0.67). The gain of U6 will change in direct proportion to changes in the carrier ref voltage. If the carrier ref voltage is set to 0 V, or it is clamped to ground because Q1 is turned on, U6's gain is minimum (zero). In turn, the modulating reference's multiplication factor is minimum (zero). The transmitter's RF output is turned off. The gain of U6 will change in inverse proportion to changes in the B+ ref (1) input. This feature eliminates the need for sophisticated filtering of the transmitter's B+ power supply and maintains the transmitter's RF output at the original level for B+ voltage variations of ±10%. 2.3.3.1.5 GAIN TRIM potentiometer R31 provides a nominal 10% adjustment in the carrier ref + audio output of U3B. It is adjusted in dual exciter applications to compensate for tolerance differences in the PDM generators of exciter A and exciter B. When it is set properly, the transmitter's RF output is the same when either exciter is selected, provided the same carrier ref is being applied. 2.3.3.2 PDM Divider The PDM divider circuit divides the 2PDM input frequency (J1-7) by two. The resulting PDM output (J1-10) is a 0 V to 15 V square wave. Unless otherwise established during the transmitter's manufacture, it should be a fixed frequency, nominally 130 kHz. 2.3.3.3 Linear Integrator The linear integrator circuit converts the PDM square wave on its input to a triangular waveform at its output. The triangular waveform has negative and positive voltage excursions of equal amplitude and duration. The long R/C time constant formed by C42/R57 ensures a linear rise and fall time. Since the R/C time constant is fixed, the waveform amplitude varies over the frequency range of PDM. The charge/ discharge time and waveform amplitude are maximum at the lowest frequency. 2.3.3.4 Integrator Peak Detector The integrator peak detector circuit detects the positive going excursions of the linear integrator's triangular waveform. A portion of the resulting positive dc voltage (nominally 1.8 V) at U8A’s output, is applied to the inverting input of differential amplifier U3A. The carrier ref + audio output of U3A is offset by this voltage which is proportional to the triangular waveform voltage peaks. This offset effectively sets the carrier ref + audio's zero power reference to the triangular waveform's peak voltage. This technique ensures no RF output is produced when the carrier ref input (J1-2) is 0 V. It also ensures the RF output is reduced to near 0 W at the 100% modulation envelope valleys when operating at the transmitter's rated carrier level.


2.3.3.5 Interphase PDM Generator The interphase PDM generator consists of two variable pulse duration generators (PDM1 and PDM2). Both produce identical 0 V to +15 V rectangular waveforms at the PDM repetition rate, but they are offset from each other by one half of the repetition rate. The waveform on/off ratio (duty cycle) is directly proportional to the carrier level and amplitude of the modulating audio. The transmitter utilizes three B+ voltage levels to maximize performance. As the RF output power is increased from 0 W (B+ voltage is 150 V), the PDM duty cycle increases proportionally. When the RF output is increased to a level where the PDM duty cycle reaches 45%, the controller/display PWB initiates a B+ voltage increase (to 250 V) and a PDM duty cycle decrease (to 27%). When the RF output is increased to a level where the PDM duty cycle again reaches 45%, the controller/ display PWB initiates a B+ voltage increase (to 350 V) and a PDM duty cycle decrease (to 32%). 2.3.3.5.1 PDM1 Generator The PDM1 generator consists of U10B, Q4, Q5, and their associated components. The compensated carrier ref + audio input from the integrator peak detector circuit is applied to differential amplifier U10B's non-inverting input, where it is compared to the triangular waveform from the linear integrator circuit. When the compensated carrier ref + audio is more positive than the triangular waveform, U10B's output is an open collector. +15 V is applied through R60 and R62 to the balanced drive formed by Q4/Q5. Q4 turns on and applies +15 V to K1-3 as the PDM1 output (Q5 is off). For the remainder of the triangular waveform's period, the compensated carrier ref + audio is less positive than the triangular waveform. U10B's output is a current-sink-to -15 V and Q4 turns off. Q5 turns on and clamps the PDM1 output to ground. The minimum 'on time' (zero RF power) occurs at the negative peaks of the triangular waveform. See Figure 2-2 for a timing diagram. 2.3.3.5.2 PDM2 Generator The PDM2 generator consists of U3C, U11B, Q6, Q, and their associated components. It operates similar to the PDM1 generator except U3C inverts the compensated carrier ref + audio input and applies it to differential comparator U11B's inverting input. The result is a PDM2 'on period' when the compensated carrier ref + audio is less positive than the triangular waveform and produces a minimum 'on time' at the positive peaks of the triangular waveform. The on/off ratio of the PDM1 and PDM2 outputs are the same, but the zero power reference change for the PDM2 output is offset, relative to the PDM1 output, by one half of the PDM repetition rate. 2.3.3.6 PDM Fault Detector The PDM fault detector circuit contains two identical voltage controlled switches (one for each PDM output) that control the 'set/'reset' status of the shutback latch circuit and, in turn, controls the on/off status of relay K1. For explanation purposes, only the PDM1 fault detector is described. 2.3.3.6.1 The PDM1 fault detector circuit consists of U12A and its associated components. R67/C58 form an integrator with a long time constant, relative to the PDM frequency. C58's charge voltage is applied to U12A's inverting input and compared to the 7.3 V reference voltage applied to its non-inverting input from voltage divider R70/R71/ R72. U12A's output is an open collector and has no influence when C58's charge voltage is less positive than the reference voltage. U12A's output will switch to a current-sink-to-ground when C58's charge voltage goes more positive than the reference voltage.


Figure 2-2 Timing Diagram for PDM Differential Amplifier 2.3.3.6.2 During normal operation, C58 will charge through R67 towards 15 V when the PDM1 output is 15 V (during its 'on time') and CR3 is reversed biased. It will instantly discharge to ground potential, through CR3, when the PDM1 output switches to 0 V (during its 'off time'). The repetition rate of the PDM1 on/off periods ensures the charge on C58 will not exceed 7.3 V, provided each PDM1 cycle contains an 'off time'. If a PDM failure occurs that produces a continuous 'on time', C58 will charge more positively than 7.3 V. U12A's output will switch to a current-sink-to-ground and toggle the shutback latch circuit to its 'set' state. 2.3.3.7 Shutback Latch The shutback latch circuit inhibits the 'on time' of the PDM outputs and, in turn, the RF output of the transmitter whenever a transmitter originated Inhibit PDM (J1-16) command is applied. This circuit provides additional protection to the transmitter's RF power stages when faults are detected or actions are initiated that may cause RF stress current thresholds to be exceeded. Its function is to de-energize K1 and disconnect the PDM 1/PDM 2 outputs from the transmitter circuits when the PDM fault detector output is a current-sink-to-ground (logic low). It also inhibits the PDM generators when relay K1 is de-energized or when a logic true inhibit PDM command is applied to J1-16. U9A/U9B form a bistable flip/flop. The flip-flop's output, at U9-3, will be 15 V (logic high) when in its 'reset' state, and a current-sink-to-ground (logic low) when in its 'set' state. Normally the inhibit PDM input and the output of the PDM fault detector circuit, which are the flip-flop's controlling inputs, are open collector. 5 V (logic high) are applied to U9-1 and U9-5 through their pull-up resistors and the flip-flop is latched in its 'reset' state. Relay K1 is held energized and the PDM outputs are applied to the transmitter circuits. If a PDM fault is sensed, the PDM fault detector circuit applies a current-sink-to-ground (logic low) to U9-5 and causes the flip-flop to switch to and latch in its 'set' state. Relay K1 de-energizes and disconnects both PDM outputs from the transmitter circuits. The PDM latch output (J1-11) is activated (5 V). This condition is maintained until the flip-flop is reset by the removal of the logic low from U9-5 (no PDM fault) and the application of logic low to U9-1 (a logic true current-sink-to-ground reset PDM command is applied to J1-1).

2.3.3.8 PDM Inhibit The PDM inhibit circuit consists of U9D, Q2, Q3, and their associated circuits. Its function is to instantly clamp the output of both PDM generators to ground (zero carrier level) whenever a logic true (current-sink-to-ground) inhibit PDM input is applied to J1-16, or when the PDM fault detector circuit senses a PDM fault and the shutback latch circuit’s flip-flop is latched in its ‘set’ state. When neither of these conditions are true, the PDM inhibit circuit has no influence. 2.3.3.9 Dump Circuit The dump circuit consists of operational amplifiers U2C, U8C, U8B, and associated components. The carrier insertion voltage at TP6 (nominally 1.4 V plus modulating audio) is applied to the inverting input of amplifier U8C (gain = 33.2) via unity gain amplifier U2C. When the modulating audio crosses the threshold on U8C’s non-inverting input, established by DUMP potentiometer R59, U8C generates a positive voltage burst for use by the transmitter’s RF power stage. 2.3.4 Power Supply Assembly The power supply assembly (1A8) is a 100 W, universal input, 24 V output power supply. The transmitter’s ac input is applied to the CN1 connector and the regulated 24 V output is provided on the CN2 connector. From there it is applied as the dc input source for the LVPS buck converter PWB. 2.3.5 LVPS Buck Converter PWB The LVPS buck converter PWB (1A9) accepts the 24 V supply from the power supply assembly and provides regulated 15 V and 5 V supplies for the exciter stage and the remaining functional blocks of the transmitter (see Figure SD-15). 2.3.5.1 Dc-Dc Converter Q1 and Q2 are fixed frequency power switching regulators. Their PWM signal outputs determine the output voltage. Q1 generates the 15 V supplies and Q2 generates the 5 V supplies. Feedback applied to pin 1 of each device adjusts the pulse width to regulate the output voltage. 2.3.5.2 Ac Sample The ac supply voltage is applied to the primary of sample transformer T1. Diodes CR8 and CR18, capacitor C5, and resistors R5, R6, and R11 provide a half-wave rectified, attenuated sample of the ac signal at J2-29 and J2-30. This sample is used by the transmitter for control and display purposes. 2.3.5.3 LVPS Failure Detector The half-wave rectified ac signal is also applied to an LVPS failure detection circuit. This circuit consists of comparators U1A and U1B, opto-coupler U2, and associated components. Zener diodes CR15 and CR16 regulate the ac signal to 9.4 V, which is used to apply a high limit reference voltage (3.4 V) to U1A’s negative input and a low limit reference voltage (2.7 V) to U1B’s positive input. Each of the low voltage power supplies are scaled and applied to both the high and low limit detectors. If a low voltage supply increases or decreases beyond acceptable limits, the output of the associated detector will switch to an open collector. Opto-coupler U2 will turn on and apply a ground potential (0 V) to the LVPS Fail output for that PWB.


2.4 AC/RF POWER STAGE The ac/RF power stage (see Figure SD-3) contains two RF power modules (A and B). Circuitry within the RF power modules convert the transmitter’s ac input to the B+ dc supply used by the RF power modules. 2.4.1 RF Power Modules Each RF power module (2A1 and 2A2 see Figure SD-16) contributes up to 550 W unmodulated RF carrier power to the transmitter's RF output. Each RF power module contains a wideband RF amplifier, a modulator, and a modulator filter. A forward converter PWB is provided to convert the ac input voltage to the high level B+ voltage used by the modulator assembly. A power module interface PWB is provided to interface control/monitor signals between the RF power modules and the exciter interface PWB as required. The RF power module outputs are applied to the RF combiner/filter stage. 2.4.1.1 Forward Converter PWB The forward converter PWB (A1 - see Figure SD-17) is a switch mode power supply that converts the transmitter’s 170-270 V ac input voltage to the B+ voltage (350/250/150 V) used by the modulator. 2.4.1.1.1 Rectifier The ac input voltage is rectified by diodes U1 and U2, providing a dc voltage across capacitors C12 through C17. Varistors RV1 through RV3 provide protection from high voltage transients. AC IND lamp DS1 provides a status indication of the ac voltage on the RF power module. 2.4.1.1.2 Switching Signal IC U3 is a high current FET driver that provides a switching PWM signal (0-18 V) to the primary of transformer T2. The secondaries of T2 control the on/off status of FETs Q1 and Q2, which in turn switch the rectified ac voltage to the primary of step-up transformer T1. 2.4.1.1.3 B+ Voltage The secondaries of step-up transformer T1 are rectified by diodes CR9, CR10, CR11, CR13, CR14, and CR15. These voltages are applied through chokes L4, L5 and L6 and combine to form the high level B+ voltage at the dc output (J4-1). Samples of the B+ voltage (resistors R9, R26 and R27) and current (transformer T3 and associated components) are applied to inputs of current mode PWM controller U8, which provides PWM switching information to regulate the B+ voltage. FETs Q4, Q5 and resistors R10, R24 and R25, in conjunction with opto-couplers U4 and U6, provide a means to adjust the attenuated voltage applied to U8, thereby adjusting the level of the B+ voltage. 2.4.1.1.4 Inhibit When an RF power module fault occurs, the Inhibit signal (J1-7) is logic high. Opto-coupler U7 turns on and inhibits the B+ voltage via U8. Opto-coupler U9 turns on causing FET Q7 to be biased off, which disables fan operation while the B+ voltage is inhibited. 2.4.1.1.5 Temperature Temperature sensor U11, operational amplifier U5:A and associated components form a temperature monitoring circuit for the RF power module. A dc voltage, representative of the temperature, is applied to Temperature output (J1-12).


2.4.1.2 Power Module Interface PWB With the exception of the B+ input to the modulator, the power module interface PWB (A2) provides the input and output connections for the associated RF power module's power amplifier and modulator. 2.4.1.3 Modulator The modulator assembly (A3) is effectively a logic level converter that converts the low level (0-15 V) logic of the PDM input to a high level (0-B+) logic PDM (B+) output. 2.4.1.3.1 13 V Power Supply The 15 V LO output (pin 1) of FET driver U1 is full-wave rectified by the bridge rectifier formed by CR1 through CR4, at the PDM frequency. The resultant dc voltage is filtered by capacitor C7 and limited to 13 V by zener diode CR5. The power supply's less positive output is referenced to the source terminal of power MOSFET Q1 via resistor R7. Therefore, the positive output is always 13 V more positive than the voltage on the FET source terminal. The 13 V output is applied to the VB (+) and VS (-) inputs of FET driver U1 as the switched gate drive for the power MOSFETs. Transformer T1 provides isolation between the high and low level signals. 2.4.1.3.2 FET Driver FET driver U1 is an integrated circuit configured to produce outputs as follows: When the HIN input is high (+1 5 V), HO output is the dc voltage applied to VB input. When the HIN input is low (0 V), HO output is the reference voltage applied to VS input. The HO output, which contains the PDM data, is applied to the gate of power MOSFET Q1 as its on/off control. 2.4.1.3.3 B+ Switching MOSFET Power MOSFET Q1 is connected to switch the B+Vdc on and off at the on/off ratio of the PDM data on U1's HO output, which is applied to its gate. The resultant PDM (B+) output contains the PDM data applied to J2-7 at a high (0-B+) logic level. Free-wheeling diode CR6 prevents negative overshoot by providing current flow when MOSFET Q1 is switched off. 2.4.1.3.4 Dump Circuit The dump circuit consists of FET Q2 and associated components. During high trough modulation peaks, the average current flowing into the modulator filter is low and the drain-source capacitance of modulator MOSFET Q1 becomes a finite factor in transmitter linearity. A pulse is applied to the modulator’s dump input (J2-9) during the -95% to –100% modulation intervals to discharge the residual capacitance on MOSFET Q1. 2.4.1.4 Modulator Filter PWB The modulator filter PWB comprises inductors L1 through L3 and capacitors C1 through C3 as well as C2 of the power amplifier (A5). These components form a low pass filter designed to pass the audio components but reject the PDM frequency. When no modulating audio information is present, the PA Volts output will be a dc voltage equal to the modulator input voltage multiplied by the duty cycle of the PDM (B+) signal. Capacitor C5 in conjunction with L3 is resonant at a frequency to provide optimal rejection of the PDM frequency.


2.4.1.5 Power Amplifier The power amplifier (A5) uses two parallel-connected pairs of MOSFETs (Q1 through Q4) to produce an unfiltered, modulated RF output. The MOSFETs are connected as cascode or ‘H’ bridge class ‘D’ amplifiers, which switch the PA volts at the RF drive frequency (refer to Figure 2-3 for a description of class D operation using power MOSFETs). RF drive splitter transformer T1 splits the RF drive signal and applies it to MOSFETs Q1 through Q4 with the required phase relationship. Diodes CR1 through CR4 prevent the output of the RF amplifier from going negative. Transistor Q5 and associated components detect the RF drive level and provide an alarm signal to the controller/display PWB. Resistors R5 through R7 provide a PA Volts Sample for front panel monitoring.

SIMPLE CLASS 'D' OPERATION If the switch is opened and closed with a 50% duty cycle, a square wave at the switching frequency will result at the filter input. If the filter is designed to pass the switching frequency, but attenuate its harmonics, a sine wave is applied to the load.

PUSH-PULL CLASS 'D' OPERATION If S1 and S2 are opened and closed with a 50% duty cycle, a square wave of current, at the switching frequency, is passed through the primary of the transformer and transformed to its secondary. If the filter is designed to pass the switching frequency, but attenuate its harmonics, a sine wave is applied to the load.

POWER MOSFET CLASS 'D' OPERATION Power MOSFETs can be used to replace the switches as depicted in the simple class 'D' operation and push-pull class 'D' operation examples. Note that the switch contacts are replaced by the phase-oriented secondaries of an RF drive transformer. Q1 corresponds to S1-A, Q2 to S1-B, Q3 to S2-B and Q4 to S2-A, as depicted in the push-pull class 'D' operation example. Q1 and Q4 turn on/off together and Q2 and Q3 turn on/off together.

Figure 2-3 Simplified Principles of Class 'D' Operation


2.5 RF COMBINER/FILTER STAGE The RF combiner/filter stage contains an RF combiner and a bandpass filter that produce the transmitter’s final RF output (see Figure SD-3). A forward/reflected power probe and an RF current probe provide samples of the transmitter’s RF output, forward power, reflected power and RF current. 2.5.1 Hybrid Combiner/Matching Transformers The outputs of the two RF power modules are applied to hybrid combiner transformer T1. The combined output of transformer T1 is applied to matching transformer T2, which steps up combiner transformer T1’s output impedance from 25 to 50 . When the RF signals applied to combiner transformer T1 are of equal amplitude and phase, no signal is applied to the Reject Load output (J2). When an amplitude or phase difference occurs, an RF voltage proportional to that difference is applied to the Reject Load output (J2). An external load connected to J2 will dissipate the reject power. 2.5.2 RF Output Filter The output of the hybrid combiner is applied, via RF filter input PWB A2A3, to an RF output filter. The RF output filter, consisting of capacitors C1 through C3 and inductors L1 through L3, is a band pass filter with a series trap tuned to the carrier frequency's third harmonic. Its nominal input and output impedance is 50 and it has a loaded Q of '2'. The filter removes unwanted harmonics from the hybrid combiner’s output and provides the transmitter's final RF output (J1). The filter also contains an RF current probe and a forward/reflected power probe. These probes monitor the RF and provide outputs that are monitored by protection circuits. Transient suppressor zener diodes A2A4CR4 through A2A4CR9 provide transient protection for the RF output. 2.5.3 RF Current Probe The RF current probe circuitry, located on the RF filter input PWB (A2A3), monitors the RF current applied to the RF output filter and produces an RF voltage proportional to the RF current. This voltage is applied to A2A4J1-11 as the RF current sample output. The RF current sample output is applied to the controller/display PWB's high RF current detector and metering circuit. This high RF current detector produces a high RF current alarm and causes the transmitter's RF output to shut back (turn off) when the RF current exceeds a threshold that represents the maximum stress current for the RF power modules. 2.5.4 Forward/Reflected Power Probe The forward/reflected power probe circuit, located on forward/reflected power probe PWB A2A4, consists of 20:1 RF current transformer T1, 80:4 RF voltage transformer T3 and associated components. These transformers form the current and voltage arms of a forward/reflected power bridge, which samples the RF output. The current flowing into the RF output passes through transformer T1’s primary. The current in T1’s secondary develops a voltage across resistors R3 through R7 that is proportional to the RF output current. The anti-phase voltage across the secondary of RF voltage transformer T3 is applied (summed) to the centre-tap of T1’s secondary. When the RF output impedance is precisely 50 , the RF current waveform is in-phase and of equal amplitude to the RF voltage waveform on one half of T1’s center-tapped secondary and equal amplitude, but 180 out-of-phase on the other half.


The in-phase voltages are summed, rectified by CR4, low-pass filtered by L3/C2/L4, resulting in a dc voltage being applied to the Fwd Pwr Sample output (J1-1). This voltage is proportional to the RF output's forward power level.

The out-of-phase voltages are summed, rectified by CR1, low-pass filtered by L1/C1/L2, resulting in a dc voltage being applied to the Refld Pwr Sample output (J1-5). This voltage is proportional to the RF output's reflected power level. T3’s secondary voltage, which is a true sample of the RF output’s voltage waveform, is also applied to the RF Sample output (J1-9). This output is applied to the remote interface PWB’s RF MONITOR OUT BNC to allow for monitoring by a modulation monitor and test equipment during maintenance. 2.6 CONTROL/MONITOR STAGE The control/monitor stage (see Figure SD-1A and SD-1B) consists of the front panel metering, controller/display PWB, remote interface PWB and optional NxLink Ethernet interface module. 2.6.1 Front Panel Metering The front panel of the exciter/control assembly (Unit 1) provides local controls and a graphic user interface to display operating status, root cause fault detection, RF power, and critical dc voltage/current levels. The front panel is divided into three sections – system diagram, diagnostic display and control. 2.6.1.1 System Diagram The system diagram is a functional flow diagram of the transmitter. Each section of the flow diagram contains an alarm lamp, which turns on when a fault occurs in that section. Refer to Section 3 of the Installation and Operation manual for a description of each lamp. If a lamp is flashing, the transmitter has entered a cutback (reduced power) mode of operation. The lamp that is flashing is likely the cause for the cutback. 2.6.1.2 Diagnostic Display The diagnostic display is a graphic user interface (GUI) that is navigated using five soft-keys. The majority of the transmitter’s local control (exciter selection, power level, etc.) and monitoring (critical parameter levels, alarm events, etc.) may be performed from menus on this display. Refer to Section 3 of the Installation and Operation manual for a detailed description of the diagnostic display. 2.6.1.3 Control Switches The control switches determine the transmitter’s control location (local or remote) and its RF status (on or off). 2.6.1.3.1 Local/Remote Selection When Local is selected, all remote control functions, except RF off, are disabled and have no influence on the transmitter's operating status or pre-set RF power levels. When Remote is selected, all front panel control functions, except RF Off, are disabled and have no influence on the transmitter's operating status or pre-set RF power levels. 2.6.1.3.2 RF On/RF Off Selection When RF On is selected (enabled in Local mode only), the transmitter’s RF power stage is enabled to provide an RF output. When RF Off is selected (enabled in Local and Remote modes), the transmitter’s RF power stage is inhibited.


2.6.2 Controller/Display PWB The controller/display PWB (1A1 - see Figures SD-4 through SD-7) performs the following functions: Produces dc voltage carrier reference outputs that determine the forward power (RF carrier)

level of the RF output. These voltages are the reference voltages for variable pulse duration modulation (PDM) generators in the exciter stage.

Monitors critical parameters and causes the carrier reference voltage to turn off (shutback)

or reduce (cutback) when fault threshold limits are exceeded. Identifies out-of-tolerance parameters when the carrier level is shutback/cutback by

providing a local visual indication or a remote electrical status output. Selects the exciter (A or B) that will provide the RF drive and PDM drive to the RF power

stage’s RF amplifiers. Determines RF power stage on/off status. Interfaces with the front panel’s diagnostic display. 2.6.2.1 Carrier Reference Voltage The carrier ref (A) (J4-14) and (B) (J4-16) outputs are applied to the interphase PDM driver PWB of each exciter to generate the PDM drive pulse that ultimately controls the RF output of the transmitter. Micro-controller U4 produces variable pulse width, 100 kHz signals as the source for the carrier ref outputs. The carrier reference filter consists of operational amplifiers U7A, U7B and associated components to form a Bessel filter with a nominal 5 Hz cut-off frequency. The carrier reference filter is provided to remove all switching components from the carrier reference line. 2.6.2.2 Alarm Threshold Circuits Certain parameters that are monitored by the controller/display PWB can initiate an alarm indication and appropriate transmitter control if an out of tolerance condition occurs. 2.6.2.2.1 Ac Supply Voltage The Ac Pwr input (J4-22) is an unregulated dc voltage that is proportional to the ac power source voltage. The input is filtered and buffered (by operational amplifier U24D) and compared to a pre-determined low ac ref fault threshold (on operational amplifier U27C). If the Ac Pwr voltage falls below this threshold, the carrier ref (A) and (B) outputs are clamped to 0 V and the shutback (A) (J5-1) and (B) (J5-2) outputs will switch to 0 V and inhibit the exciter stage’s modulator drive. The transmitter's RF output is turned off (shutback) and will remain off until the ac power voltage is restored to an acceptable voltage. The system diagram’s AC Mains lamp will display a fault condition. An Ac Sample signal is applied to A/D converter U28 for application to the front panel’s diagnostic display. 2.6.2.2.2 Reflected Power Monitor The refld pwr input (J7-4) is a dc voltage that is proportional to the reflected power sensed at the transmitter's output. The input is filtered and applied to the Ext Refld Pwr Sample output (J1-5) for remote monitoring.


The signal is then buffered (by operational amplifier U33A) and compared to a pre-determined refld pwr shtbk ref fault threshold (on operational amplifier U35A). When the reflected power exceeds 150 W, the refld pwr input is more than the fault threshold. The carrier ref (A) and (B) outputs will be clamped to 0 V and the shutback (A) (J5-1) and (B) (J5-2) outputs will switch to 0 V and inhibit the exciter stage’s modulator drive. A clock pulse is also applied to an alarm count/cutback circuit in complex programmable logic device (CPLD) U14. The RF output will instantly shut back (turn off). This signal is also monitored by operational amplifiers U35B and U35C, which determine the amount of cutback applied to the RF output. The system diagram’s Output Network lamp will display a fault condition. A Refld Pwr Sample signal is applied to A/D converter U28 for application to the front panel’s diagnostic display. Turning off the RF output will result in the refld pwr input being reduced to 0 V. The carrier ref (A) and (B) outputs are restored to their pre-shutback levels, the shutback A and B outputs return to open collector, and the RF output is restored at an exponential rate. If the fault threshold is exceeded before the pre-set power level is reached, the shutback cycle is repeated. If four or more shutback cycle clock pulses are applied within any five-second period, the carrier ref outputs is cutback (reduced) until the carrier level is cutback (reduced) to a level that results in an acceptable reflected power. When the transmitter has entered cutback mode, the system diagram’s Output Network lamp will flash on and off. When the refld pwr input returns to or is maintained at a level that is less than the fault threshold, the shutback outputs will return to open collector but the system diagram’s Output Network lamp will continue to display a fault as a maintenance aid. The lamp will remain on until reset by the diagnostic display menu. 2.6.2.2.3 RF Current Monitor The RF current input (J7-8) is an RF voltage that is proportional to the total RF current being applied to the RF output filter by the RF power modules. The input is filtered and buffered (by operational amplifier U33B) and compared to a pre-determined RF current ref fault threshold (on operational amplifier U35D). When the RF current exceeds the fault threshold, the carrier ref (A) and (B) outputs are clamped to 0 V and the shutback (A) (J5-1) and (B) (J5-2) outputs will switch to 0 V and inhibit the exciter stage’s modulator drive. A clock pulse is also applied to CPLD U14’s alarm count/cutback circuit. The RF output is instantly shutback (turned off). The system diagram’s Output Network lamp will display a fault condition. An RF Current Sample signal is applied to A/D converter U29 for application to the front panel’s diagnostic display. Turning off the RF output will result in the RF current input being reduced to 0 V. The carrier ref (A) and (B) outputs are restored to their pre-shutback levels, the shutback A and B outputs return to open collector, and the RF output is restored at an exponential rate. If the fault threshold is exceeded before the pre-set power level is reached, the shutback cycle is repeated. If three or more shutback cycle clock pulses are applied within any three second period, the carrier ref outputs are cutback (reduced) until the carrier level is cutback (reduced) to a level that results in an acceptable RF current level. When the transmitter has entered cutback mode, the system diagram’s Output Network lamp will flash on and off. When the RF current input returns to or is maintained at a level which is less than the fault threshold, the shutback outputs will return to open collector but the system diagram’s Output Network lamp will continue to display a fault as a maintenance aid. The lamp will remain on until reset by the diagnostic display menu.


2.6.2.3 Sample Monitoring Circuits In addition to the parameters described in paragraph 1.6.2.2, various parameters are applied to the controller/display PWB for local (via the front panel’s diagnostic display) and/or external (via the remote interface PWB) monitoring. In most cases, these parameters also have associated alarm detection circuitry, but it is not resident on the controller/display PWB. 2.6.2.3.1 B+ Voltage The B+ (A) (J4-24) and B+ (B) (J4-26) inputs are dc voltages which represent the positive dc voltage applied to RF power modules A and B as their high current voltage source. The inputs are filtered and buffered by operational amplifiers U24B and U37A. B+ (A) Sample and B+ (B) Sample signals are applied to A/D converter U29 for application to the front panel’s diagnostic display. The ORed output of the B+ sample inputs is applied to the Ext B+ Sample output (J1-19), then applied to the remote interface PWB for external monitoring. 2.6.2.3.2 PDM Drive The PDM (A) (J4-10) and PDM (B) (J4-12) inputs are pulses which represent the PDM signal applied to RF power modules A and B. The inputs are buffered by operational amplifiers U36D and U36B and then filtered through operational amplifiers U38B and U38D and associated components. PDM (A) Sample and PDM (B) Sample signals are applied to A/D converter U28 for application to the front panel’s diagnostic display. 2.6.2.3.3 Dc Current The Dc Current (A) (J8-19) and Dc Current (B) (J8-39) inputs are dc voltages which represent the dc current being drawn by RF power modules A and B. The inputs are buffered by operational amplifiers U36A and U36C and then filtered through operational amplifiers U38C and U38A and associated components. Dc Current (A) Sample and Dc Current (B) Sample signals are applied to A/D converter U28 for application to the front panel’s diagnostic display. The ORed output of the Dc Current Sample inputs is applied to the Ext Dc Current Sample output (J1-17), and then applied to the remote interface PWB for external monitoring. 2.6.2.3.4 PA Voltage The PA Volts (A) (J4-6) and PA Volts (B) (J4-8) inputs are dc voltages which represent the voltage applied to the power amplifiers in RF power modules A and B. The inputs are buffered by operational amplifiers U33C and U33D and then filtered through operational amplifiers U37B and U37D and associated components. PA Volts (A) Sample and PA Volts (B) Sample signals are applied to A/D converter U29 for application to the front panel’s diagnostic display. 2.6.2.3.5 Forward Power The Fwd Pwr input (J7-2) is a dc voltage that represents the forward power at the transmitter’s RF output. The input is buffered by operational amplifier U32D and then filtered through operational amplifier U26B and associated components. A Fwd Pwr Sample signal is applied to A/D converter U28 for application to the front panel’s diagnostic display. The Fwd Pwr input is also applied to the Ext Fwd Pwr Sample output (J1-3), then applied to the remote interface PWB for external monitoring. The buffered Fwd Pwr signal is low-pass filtered through operational amplifier U32B and associated components and applied to the Ext Audio output (J1-7), then applied to the remote interface PWB for external monitoring. The Ext Mod % Sample and Audio (Speaker) outputs are not used in J1000 transmitters. 2.6.2.3.6 Low Voltage Power Supplies Attenuated, buffered samples of all low voltage dc power supplies (+24 V, 15 V and 5 V) are applied to A/D converters U28 and U29 for application to the front panel’s diagnostic display. Lamps DS9 through DS13 indicate the presence of these voltages.


2.6.2.4 Microcontroller Microcontroller IC U4 interfaces between the diagnostic display and its associated soft-keys. It generates the Carrier Ref signal (see paragraph 1.6.2.1), which ultimately determines the forward power level of the transmitter. It also acts as an internal and external serial interface for transmitter alarm and status signals. 2.6.2.5 CPLD Complex Programmable Logic Device (CPLD) U14 continuously reads digital inputs for all transmitter alarm events. It is programmed to perform root cause detection of a fault as well as high-speed fault protection. Depending on the nature of the fault, the CPLD generates transmitter Shutback outputs (J5-1 and J5-2) or various digital control/inhibit signals via a parallel data buss. 2.6.3 Remote Interface PWB The remote interface PWB (1A2 - see Figures SD-8 through SD-10) performs the following functions: Buffers all external transmitter remote control inputs and transmitter remote status/alarm

outputs. Provides buffered, analog sample voltages proportional to the B+ supply voltage, total dc

current, audio, forward power, and reflected power for external monitoring. Conditions the audio (analog or DAB) input’s gain and provides filtering and modulation

protection. Provides monitoring samples of the transmitter’s RF output (both analog and DAB). The

magnitude of the analog sample is automatically adjusted to ensure a relatively constant voltage, nominally 1V RMS, regardless of RF output level.

Provides the connection for the system’s external interlock circuit between TB2-15 and

TB2-16. 2.6.3.1 Remote Inputs RFI filtering is provided on all control input lines to ensure transmitter operation is not interrupted due to RF pick-up on control lines. Opto-couplers are provided to buffer/isolate the external circuits and prevent any unwanted transients from affecting transmitter operation. The position of shorting jumpers E8 through E22 and E27 allow the control inputs to be configured to operate from a single-ended or differential input. Refer to section 2 of the Installation and Operation manual for detailed description on single-ended versus differential inputs. 2.6.3.2 Remote Outputs Remote alarm/status outputs are provided on terminals of the remote interface PWB. A darlington transistor for each alarm/status output provides a negative logic (current-sink-to-ground) output when a logic ‘true’ (alarm condition or active status) exists. The switching circuit provides an open collector during logic ‘false’ conditions (non-alarm or non-active status condition) and has no influence on the external monitoring circuit. Each monitoring circuit must present impedance between the switching device and a positive dc voltage source that will result in a current flow of not more than 50 mA. +24 V is available for use by the remote monitoring circuits on TB4-18.


2.6.3.3 Audio Input The transmitter’s audio input is applied to the AUDIO INPUT terminals (TB2-12/13/14), for analog audio, or to RJ45 connectors J2 [MAG (HD-R)] and J3 [PHASE (HD-R)], for HD-R operation. The audio signal is then applied to the balance/unbalance circuit. The position of shorting jumpers E1 and E2 determine the amplitude modulating source – HD-R or normal AUDIO program. 2.6.3.4 Balance/Unbalance Circuit The balance/unbalance circuit, which converts the balanced audio input or HD-R magnitude input to an unbalanced signal, consists of U2A or U5A and its associated components. The output of differential amplifier U2A or U5A is an unbalanced audio that is a positive voltage for positive half cycles and a negative voltage for negative half cycles. Any unwanted noise transients that are induced on the audio input will be in-phase and of equal amplitude. Since the transients are in-phase and of equal amplitude, they have no influence on U2A's or U5A’s output and they will not appear at U2A's or U5A’s output. 2.6.3.5 Zero Crossing Detectors The audio zero crossing detector consists of U11B, Q1, CR1, and associated components. The HD-R zero crossing detector consists of U9A, Q6, CR38, and associated components. These circuits are the +15 V charge voltage sources for C32 during the negative audio half-cycles. During positive audio half-cycles they are effectively open circuit and have no influence on the charge state of C32. A small dc bias (0.3 V) is present on U11B’s non-inverting input or U9A’s inverting input for HD-R and DRM operation. 2.6.3.6 Modulation Level Detector The modulation level detector circuit monitors the on/off times of the Fwd Pwr Sample output for excessive on times. It automatically inhibits a portion of any modulating audio's positive going half-cycle that would cause excessive 'on times' and result in the stress current threshold of the transmitter's RF power amplifier stages being exceeded. The circuit consists of comparators U11C, U11D, U12A, U12B, U12C, U12D and their associated components. It provides a discharge path to -15 V for C32 when the 'on time' of the Fwd Pwr Sample signal will result in modulation peaks that exceed safe operating levels 2.6.3.6.1 The Fwd Pwr Sample input, applied to the inverting inputs of each comparator, is a varying positive dc voltage directly proportional to the RF output's modulation envelope. The audio component is synchronized with the audio output of U11B and is the most positive at the peak of the modulating audio's positive half-cycle. 2.6.3.6.2 Each comparator has a reference voltage applied to its non-inverting input that represents the RF stress current threshold for a specific carrier level/audio amplitude/audio frequency combination (see Table 2-1). SET THRESHOLD potentiometer R45 is adjusted to precisely set the threshold voltages, when the PWB is installed in a transmitter.


2.6.3.6.3 When the voltage representing the modulation envelope exceeds the RF stress current threshold of a comparator, that comparator connects its output resistor to -15 V and provides a discharge path for C32. The time for C32 to discharge to a negative voltage is dictated by the number of resistors connected to -15 V (modulation amplitude) and the period of time they are connected (audio frequency). C32's discharge time (dictated by the R/C time constant) is progressively faster as the modulation depth increases (more comparator thresholds are exceeded) and it has a longer time to discharge as the audio frequency decreases. Refer to Table 2-1 for the duration of a positive half-cycle at the lowest unaffected audio frequency for specific modulation depths. Table 2-1: Peak Modulation Limit Threshold

Mod Depth Peak)

Lowest Unaffected Freq.(Hz) Duration (ms)

85% 10 50.0 95% 11 46.6 105% 20 25.6 115% 32 15.4 125% 56 8.9 135% 96 5.2

2.6.3.7 Audio Chopper The audio chopper circuit consists of U11A, Q2, Q7, and their associated components. It inhibits some portion of positive audio half-cycles that cause modulation peaks/durations that exceed the RF stress current threshold of the transmitter's RF power amplifiers. It accomplishes this by clamping the modulating audio to ground whenever the charge voltage on C32 switches from a positive value to a negative value and retains this state until C32's charge voltage returns to a positive value at the end of the positive audio half-cycle. When C32 has a positive voltage charge, U11A's non-inverting input is more positive than its inverting input. U11A's output is an open collector. Q2 and Q7 are reverse biased and have no influence on the modulating audio or HD-R. Q4 is also reverse biased. The mod prot/audio limit output (J1-31) is open collector (logic negative state). When the modulation level detector circuit provides C32 a discharge path to -15 V (because one or more RF stress current thresholds have been exceeded) for a long enough period of time to achieve a negative voltage charge, U11A's non-inverting input will go less positive than its inverting input. U11A's output is a current-sink-to -15V and causes Q2, Q7 and Q4 to be forward biased (turned on). The modulating audio or HD-R magnitude signal is clamped to ground by Q2 or Q7 until the start of the next negative audio half-cycle (for the balance of the current positive audio half-cycle), when the zero crossing detector circuit provides a low impedance source to +15 V and charges C32 to a positive value. The Mod Prot/Audio Limit output is a current-sink-to-ground (logic true state) for each offending positive audio half-cycle. The system diagram’s Exciter lamp will flash on and off when this circuit is active. 2.6.3.8 Audio Gain U9B is connected as a unity gain, buffer amplifier. AUDIO GAIN potentiometer R23 is adjusted for the desired modulation depth when the interphase PDM driver PWB is installed in its host transmitter. It has sufficient range to set the modulation depth at 100% when the audio input is between 0 dBm and +12 dBm.


2.6.3.9 Audio Filter The audio filter circuit is a low pass filter with a -1.0 dB, high frequency roll-off at one of four user-selected frequencies. The AUDIO FILTER switch S1 has settings to select one of four roll-off frequencies (16 kHz, 13.5 kHz, 10.5 kHz or 7.5 kHz). The high frequency roll-off selection is normally dictated by complex factors, such as an antenna with sideband limitations, square wave overshoot, or the equipment that pre-processes the audio. The AUDIO FILTER switch and audio filter are bypassed (using shorting jumpers E3 and E4) when digital program input is used. 2.6.3.10 RF Monitor Level The RF Monitor In input (J13) is applied to a group of series resistors, each in parallel with contacts of a relay switching circuit. The serial data out (2) signal, applied to the A input (pin 14) of 8-bit shift register U39, and represents the carrier reference level, hence the transmitter’s RF output. U39’s parallel Q outputs energize the appropriate relay(s) to provide 1.0 V RMS into a 1,000 or 50 load as the RF Monitor Out output (J14), when the RF output is between 100 W and 1,100 W. 2.6.3.11 Magnitude Gain MAG GAIN potentiometer R36 is adjusted for the correct magnitude signal when connected to an NE IBOC exciter for HD-R operation. 2.6.4 NxLink Ethernet Interface Module (Optional) See the NxLink manual. An optional NxLink Ethernet interface module (U200) converts the internal serial protocol to Ethernet for external interfacing. When U200 is used, internal transmitter wiring is provided to supply the module’s +15 V power supply.

J1000 REPAIR MANUAL Section 3 COMPONENT LEVEL TROUBLESHOOTING

3.1 INTRODUCTION The information provided in this section is intended to assist an experienced electronic technician in fault diagnosis and isolation of a problem to the component level. It is assumed that system level troubleshooting as outlined in the Installation and Operation manual has been performed and the problem has been isolated to a particular PWB or assembly. 3.2 ELECTROSTATIC DISCHARGE PROTECTION The transmitter's PWBs/assemblies contain semiconductor devices that are susceptible to damage from electrostatic discharge (ESD). The following precautions should be taken when handling an assembly that contains these devices:

NOTE Electrostatic energy is produced when two insulating materials are rubbed together. A person wearing rubber-soled shoes, walking across a nylon carpet or a waxed floor can generate an extremely large electrostatic charge. This effect is magnified during periods of low humidity. This high voltage may damage semiconductor devices such as integrated circuits, field-effect transistors, thyristors and Schottky diodes unless adequate precautions are taken. 3.2.1 Discharging of Personnel Personnel must be electrically discharged by a suitable ground system (anti-static mats, grounding straps) when removing an assembly from the transmitter and while handling the assembly for maintenance procedures. 3.2.2 Handling/Storage The assembly should be placed in an anti-static bag when it is not installed in a host transmitter or when it is not being subjected to maintenance procedures. Electronic components should be stored in anti-static materials. 3.2.3 Tools/Test Equipment Testing and maintenance equipment, including soldering and unsoldering tools, should be suitable for contact with static sensitive semiconductor devices. A 40 W, temperature controlled soldering iron is recommended.

Page 3-2 J1000 Repair Manual Issue 5.0 Section 3 Component Level Troubleshooting

3.2.4 Stress Current Protection Precautions should be taken to ensure the static sensitive semiconductor devices are protected from unnecessary stress current. This is achieved by ensuring: Current is not flowing when an electrical connection is broken. Voltages are not present on external control/monitoring circuits when they are connected. 3.3 COMPONENT REPLACEMENT PRECAUTIONS When replacing a part on a PWB or assembly, the following precautions must be taken: Ensure all PWBs are at least two-sided and contain through-hole plating. Use of

excessive heat or excessive mechanical force can damage the PWB. Multi-layer PWBs are more susceptible to damage than two-sided PWBs.

DO NOT replace components while the PWB/assembly is mounted in the transmitter. When removing a defective component, cut the body from the legs before unsoldering the

component. This will reduce the heat stress to the PWB’s traces. Use a solder removal tool or solder wick whenever possible to remove the solder from the

component’s legs before removing the device. Pre-form the legs of a replacement component to fit the PWB hole spacing. This also

applies to ICs that mount in sockets. For mechanically fastened components, such as power MOSFETs, secure the

mechanical connection before soldering the legs to reduce the stress on the solder connection.

3.4 SURFACE MOUNT TECHNOLOGY Surface mount technology (SMT) enables more efficient use of board space than with through-hole technology, but component replacement is more difficult. It is not practical to place SMT components in the transmitter spares kit because of their small size. f the repair site is not already equipped to handle surface-mount technology, the following guidelines will aid in component replacement: 3.4.1 Location of Parts SMT components are predominantly on controller/display PWB 1A1 and remote interface PWB 1A2. The RF synthesizer PWB(s) (1A4 and, if installed, 1A6) has two SMT integrated circuits. SMT components are 0603 – 6 mm x 3 mm.


3.4.2 Soldering Guidelines The following guidelines are provided to aid the maintainer when soldering SMT components on a PWB: (a) Recommended soldering aids:

needle tip for soldering iron SMT solder (low melting point, fine diameter) water-soluble, ‘no-clean’ solder flux pen magnifying glass steady hand

(b) Ensure pads are sufficiently cleaned, using solder braid. (c) Apply a thin layer of solder flux on the pads. (d) For ICs, place the IC on the pads, noting alignment, and gently press it in place. The flux

should have enough adhesion to hold the chip in place. (e) Carefully solder one corner pin, then verify the IC's alignment. Solder the opposite corner

pin, then verify alignment again. (f) If alignment is correct, carefully solder each pin, in order, around the IC. (g) If a solder bridge occurs, use a very fine solder wick to remove it. 3.5 FET CHECKING/REPLACEMENT The transmitter contains many FETs and other switching semiconductor devices. The FETs most likely to fail are located on RF power modules A (2A1) and B (2A2). In the case of a failure caused in the RF power module, it is recommended the following devices be checked and, if necessary, replaced: power MOSFET Q1 (Nautel Part # QAP49) of modulator A3 power MOSFETs Q1 through Q4 (Nautel Part # QAP49) of power amplifier A5 FETs Q1 and Q2 (Nautel Part # QR54) of forward converter PWB A1. (a) Unsolder the gate pins of the device under test and all parallel devices. Refer to the

assembly’s electrical schematic in Section 6 to determine the parallel devices, if applicable. Refer to the assembly’s detail drawing in Section 7 to verify device pin-out.

NOTE

A MOSFET under test must be turned on by applying a dc voltage between its gate and source terminals. Some digital multimeters have sufficient dc voltage on their test leads when set to ‘diode’ or ‘resistance’ positions. If the digital multimeter being used does not have sufficient voltage (9V battery recommended), an alternate dc voltage source must be obtained.


(b) Turn off the suspect FET and all parallel devices by shorting the gate to source. Using a digital multimeter, momentarily place the negative lead on the gate pin and positive lead on the source pin for each FET in the circuit.

(c) Measure the drain-source resistance with positive lead on the drain and the negative

lead on the source. Digital multimeter reading will indicate an open circuit. (d) Measure the drain-source resistance with the negative lead on the drain and the positive

lead on the source. Digital multimeter reading will indicate a diode pedestal. (e) If the requirements of steps (c) and (d) are not met, replace the device as detailed in

steps (i) through (m). (f) Turn on the device under test by placing the positive lead on the gate and the negative

lead on the source. (g) Measure the drain-source resistance with the positive lead on the drain and the negative

lead on the source. Digital multimeter reading will indicate a short circuit. (h) If the requirement of step (g) is met, the FET is operational. Turn it off and verify as

detailed in steps (b) and (c), and then proceed to the next suspect device. If the requirement of step (g) is not met, replace the device as detailed in steps (i) through (m).

(i) Unsolder the drain and source pins of the defective device. (j) Remove the hardware securing the device in place and remove the defective device.

Ensure the associated heat sink surface on the input PWB is cleaned.

NOTE FETs are static sensitive. Ensure replacement devices are handled in a manner that protects the FETs from static.. (k) Apply a thin, even coat of thermal compound on the bottom of the new device. (l) Reinstall the device on its associated, cleaned heat sink using the hardware removed in

step (j). The Belleville (cupped) washer must be replaced with a new washer (Nautel Part # HZ48, located in ancillary kit). Both sides of the insulator (if replaced) should have a thin, even coat of thermal compound applied. Refer to the assembly’s detail drawing in Section 7 to verify the hardware orientation for the device being replaced.

(m) Using a torque screwdriver, tighten mounting hardware to the value (typically 3 to 4 inch-

pounds) specified on the assembly’s detail drawing in Section 7, ensuring that the pins of the device are aligned with their corresponding solder terminals. Solder the pins to their associated terminals.


3.6 TROUBLESHOOTING REFERENCE DATA Typical waveforms are provided for critical signals to assist in isolating a fault to a particular component or circuit. This data can only be verified when the referenced assembly is still installed in the transmitter. Electrical schematics for all PWBs and assemblies are provided in Section 6 of this manual.

WARNING Nautel does not recommend troubleshooting the RF power module’s forward converter PWB (2A1A1 or 2A2A1) while the transmitter is turned on. Voltages that are hazardous to life are present near the step-up transformer (T4) on the PWB.

NOTE

The data provided in this section is intended to represent the nominal level only. Component tolerances and carrier frequency may cause slight differences in the measured and presented data. For voltage levels dependent on the level of another parameter, that parameter's level has been noted next to the test voltage. All measurements/waveforms have been recorded with the transmitter output power set to 1,000 W, unless otherwise specified. Test point references are included with each waveform’s title.

4.1 INTRODUCTION This section contains reference designation lists that provide descriptive and provisioning information for all electrical and mechanical parts that have an assigned reference designation and form a part of the subject equipment. 4.2 FAMILY TREE Figure 4-1 depicts the family tree for the subject equipment. It is based on the descending order of the reference designation hierarchy and identifies all assemblies that have an assigned Nautel configuration control number. 4.3 HOW TO LOCATE INFORMATION FOR A SPECIFIC PART To locate the information for a specific part, the assigned reference designation for the part must be known. In addition, the Nautel configuration control number (e.g., NAP31/02A) assigned to the assembly containing the part or the full reference designation, including the reference designation of all higher assemblies, must be known. 4.3.1 When Nautel Configuration Control Number Is Known: When the Nautel configuration control number is known, the information for a part can be located as follows: Refer to the family tree (Figure 4-1) and identify the block(s) associated with the Nautel

configuration control number. At the bottom of each family tree block, a reference is made to SEE PART NUMBER INDEX TABLE. Locate the part's reference designation in the identified reference designation list in this section, noting they are sorted alphanumerically.

4.3.2 When Ref Des Is Known: When the full reference designation is known, the information for a part can be located as follows: Refer to the family tree depicted in Figure 4-1 with the full reference designation. Follow the family tree branches to the block that represents the lowest level assembly

assigned a Nautel configuration control number. Then locate the part number index table for that Nautel configuration control number.

Locate the part's reference designation in the specified table.

Page 4-2 J1000 Repair Manual Issue 5.0 Section 4 Parts Information

4.4 REFERENCE DESIGNATION LISTS Individual reference designation lists are provided for: assemblies that are assigned an alpha-prefixed Nautel nomenclature (e.g., NAPC143B/01)

cable harnesses that are assigned a numbered Nautel part (e.g., 197-8060)

optional kits that are assigned a numbered Nautel part (e.g., 197-3005) To obtain the full reference designation for a specific part the Nautel configuration control number must be located in the family tree (Figure 4-1) to include the reference designation of all higher level assemblies. The reference designation lists, which are titled and presented in alphanumeric order, are divided into columns to aid in locating specific information. 4.5 COLUMN CONTENT The following paragraphs provide an explanation of the purpose and contents of each column in the part number indexes. 4.5.1 Ref Des Column The ‘ref des’ column contains the reference designation for a specific part. These designations are assigned in accordance with the requirements of American National Standard Specification ANSI Y32.16. 4.5.2 Description Column This column contains the name and descriptive information for each part. The key word is presented first, followed by the adjective identifiers. When the description is 'See Family Tree for Assembly Nomenclature', the associated part is subject to its own part index table or is contained in an optional kit’s list. Look up the reference designation list title (nomenclature) and the reference designation of the associated part in the family tree (Figure 4-1) to determine where to locate its part information. 4.5.3 Nautel # Column This column contains the Nautel number assigned to each part. This number is Nautel's drawing number for Nautel manufactured parts, Nautel's configuration control number for assemblies that are under configuration control management, or Nautel's inventory management number for purchased parts. When a Nautel configuration control number (e.g. NAPD*) is referenced in this column, the associated ref des item is subject to its own part index table. 4.5.4 Vendor # Column This column contains an original equipment manufacturer's part number for a part. A single part number is listed for each part, even though there may be more than one known manufacturer. The listed number is Nautel's usual or preferred choice. The use of this number does not restrict Nautel from selecting and using commercial equivalents during manufacture, where their use will not degrade circuit operation or reliability.


4.5.5 OEM Code Column This column typically contains a five digit coded group as the original equipment manufacturer's (OEM) identifier. The code was extracted from Cataloging Handbook H4/H8 - Commercial and Government Entity (Cage) Code. Manufacturers that were not listed in the catalog when this listing was compiled have been assigned a unique five-letter code. This code is assigned arbitrarily and has no other significance. The manufacturers identified for parts that have JAN or MIL part numbers are Nautel's normal supply source for that part.

NOTE OEM code 37338 is listed for parts manufactured by Nautel or to a Nautel control drawing. United States of America customers should refer all replacement part orders to Nautel Incorporated (OEM code 57655). 4.6 OEM CODE TO MANUFACTURER CROSS-REFERENCE The OEM (CAGE) codes listed in the reference designation lists are representative of the original equipment manufacturers of those parts. To determine a specific part’s manufacturer contact information, enter the five-character OEM (CAGE) code for that part in the following website: https://www.bpn.gov/bincs/begin_search.asp After entering the OEM (CAGE) code number, manufacturer pertinent information (address, telephone number, fax number, etc.) will be displayed. Please contact Nautel if a part cannot be obtained (see also ON-LINE PART QUOTES in the Warranty section of this manual). 4.6.1 Manufacturer’s Index For customers without web access, Table 4-1 provides a cross-reference from the original equipment manufacturer’s (OEM) codes to the manufacturer’s name. The listing is sorted alphanumerically by the OEM code. 4.7 COMMON ABBREVIATIONS/ ACRONYMS The following abbreviations/acronyms may appear in the Description of Part column: SMT - Denotes item is designed to be installed using Surface Mount Technology. MTA - Denotes item is a Mass Termination Assembly connector. SIP - Single In-line Package DIP - Dual In-line Package IDC - Denotes item is an Insulation Displacement connector for ribbon cable.

J1000 Repair Manual Page 6-1 Section 6 Electrical Schematics Issue 5.0

J1000 REPAIR MANUAL Section 6 ELECTRICAL SCHEMATICS

6.1 INTRODUCTION This section contains electrical schematics for the subject equipment. Block diagrams, simplified electrical schematics, and logic diagrams may also be included. Refer to Table 6-1 for an itemized listing. 6.2 COMPONENT VALUES Unless otherwise specified on the logic/ schematic diagram, the following applies: Resistor values are shown in ohms ().

(K = 1000 and M = 1 000 000). Resistor power ratings are not shown when less than 0.5 W. Capacitor values are shown in microfarads (F). Unidentified diodes are part number 1N4938. 6.3 GRAPHIC SYMBOLS The graphic symbols used are in accordance with American National Standard ANSI Y32.2-1975 - Graphic Symbols for Electrical and Electronic Diagrams. 6.4 LOGIC SYMBOLS The logic symbols used on electrical schematics and logic diagrams are in accordance with American National Standard ANSI Y32.14-1975 - Graphic Symbols for Logic Diagrams. 6.5 REFERENCE DESIGNATIONS Reference designations were assigned in accordance with American National Standard ANSI Y32.16-1975 - Reference Designations for Electrical and Electronic Parts and Equipment. Each electrical symbol is identified with its basic reference designation. To obtain the full reference designation for a specific part, this basic identifier must be prefixed with the reference designation assigned to all higher assemblies. 6.6 UNIQUE SYMBOLOGY Nautel utilizes unique symbology on electrical schematics to describe two-state (logic) inputs/outputs that differ from those inputs/ outputs having only one distinct state or multiple states (analog). 6.6.1 Type of Inputs/Outputs On electrical schematics, names used to describe two-state (logic) inputs/outputs are prefixed by a '#'. Those inputs/outputs representing a one-state or analog signal will have no prefix.

Page 6-2 J1000 Repair Manual Issue 5.0 Section 5 Electrical Schematics

6.6.2 Logic Level/Convention The '#' prefix identifies an input/output that has two distinct states - 'high' and 'low'. A suffix, '+' or '-', identifies the active (true) state of the input/output. The 'high' (+) is the more positive of the two levels used to represent the logic states. The 'low' (-) is the less positive of the two levels used to represent the logic states. Two types of logic, positive and negative, may be represented on a particular schematic. In positive logic, 'high' represents the active (true) state and 'low' represents the inactive (false) state. In negative logic, 'low' represents the active state and 'high' represents the inactive state. 6.7 IDENTIFICATION OF SCHEMATIC DIAGRAMS A number that is both the figure number and the page number identifies each illustration in this section. The numbers are assigned sequentially and are prefixed by the letters 'SD-'. The electrical schematics/logic diagrams included in this section are listed in Table 6-1. 6.8 STRUCTURE OF SCHEMATICS The electrical schematics are structured in a hierarchical format that is based on function and signal flow. Wherever practical, the signal flow is from left to right. Inputs normally originate on the left-hand side and outputs will extend to the right-hand side. Exceptions are shown by an arrow indicating the direction of signal flow.

NOTE The physical location of a part/assembly was not necessarily a factor when a schematic was drawn. The full reference designation assigned to a part/assembly, in conjunction with the family tree in Figure 4-1 and the assembly detail drawings in section 7, will identify its location. Figures SD-1 through SD-3 identify each major stage and its detailed interconnection. Each stage contains cross-references that identify which block is the signal source for inputs or the destination for outputs. When a sub-function is treated as a block in Figures SD-1 through SD-3, its detailed circuit information is included in its own schematic drawing(s), also included in this section. 6.9 LOCATING THE SCHEMATIC DIAGRAM(S) FOR A FUNCTIONAL BLOCK The text inside a functional block provides the key to locating its schematic diagram(s). When a functional block is assigned a reference designation, refer to the family tree depicted in Figure 4-1 and follow the family tree branches to the block that contains the reference designation and associated Nautel nomenclature (e.g., NAP31/02A). Refer to Table 6-1 with the Nautel nomenclature number and/or the description to identify the appropriate figure number(s). 6.10 LOCATING A PART/ASSEMBLY IDENTIFIED ON A SCHEMATIC The full reference designation assigned to a part/assembly is the key to physically locating that part/assembly.

NOTE Full reference designations contain the assembly hierarchical coding. When the end item is divided into units (cabinets), the first coding is a unit number (1, 2, 3, etc). When the end item is divided into assemblies, the first coding is an assembly number (A1, A2, A3, etc). If a unit or an assembly is divided into sub-assemblies, assembly coding that identifies assembly relationship (1A1, A2A1, A2A1A1, etc) is added.

J1000 Repair Manual Page 6-3 Section 6 Electrical Schematics Issue 5.0

Refer to the family tree depicted in Figure 4-1 with the full reference designation and follow the family tree branches to the appropriate block, noting the name and Nautel nomenclature number of all higher assemblies in the path.

NOTE The drawings in Section 7 depict the assembly detail of the transmitter and its modules/ assemblies. Refer to Table 7-1 with the name and Nautel nomenclature number of each family tree block in the path, starting at the highest assembly (normally Figure MD-1) and determine the figure number(s) for that assembly. Refer to the referenced figure and locate the next lower level assembly. Repeat this procedure until the location of the required part/assembly is found. Table 6-1: Electrical Schematics

J1000 REPAIR MANUAL Section 7 MECHANICAL DRAWINGS

7.1 INTRODUCTION This section contains mechanical drawings for assemblies of the subject equipment. Dimensional drawings may be included. Refer to Table 7-1 for an itemized list. Assembly detail drawings for assemblies/ modules that have separate maintenance manuals are not included. Refer to the appropriate maintenance manual for the assembly detail of these assemblies. 7.2 LOCATING ASSEMBLY DETAIL DRAWINGS Each illustration in this section is identified by a number that is both the figure number and the page number. The numbers are assigned sequentially and are prefixed by the letters 'MD-'. Drawings in this section are listed in Table 7-1. 7.3 CONTENT OF MECHANICAL DRAWINGS Mechanical drawings are illustrations that depict the location of electrical components and show assembly outline detail. Dimensional information is included, where appropriate. When a module/assembly is the subject of its own assembly detail drawing and it is also shown in a higher level assembly, the detail depicted in the higher level assembly may have minor differences from the module/ assembly actually installed. In this case, always refer to the assembly detail drawing of the module/assembly for detailed information. Table 7-1: Mechanical Drawings
