1. These adjustable dipole antennas are particularly suited for making accurate site attenuation measurements, such as thoseoutlined in the FCC’s OST-55 bulletin. They can also be used for making measurements of emissions from the equipment undertest (EUT). Broadband antennas, such as biconical and log periodic antennas, are typically used for emissions measurements ofthe EUT because of their ease of use.

2. MIL-STD radiated emission 02 tests can be performed with either linearlypolarized antennas, such as the log periodic, or circularly polarized antennas, such asthe conical spiral. Linear antennas offer slightly better gain and antenna factor, butthey require separate scans over the full frequency range once in horizontal polarizationand again in vertical polarization. While circularly polarized antennas typically areslightly less sensitive, they allow the measurement to be made in a single scanbecause they can receive signals that have either horizontal or vertical polarization.
3. The HP 8449B microwave preamplifier offers improved sensitivity for microwaveemissions measurements. With improved sensitivity, wider receiver bandwidths canbe used, result in faster measurement times.

HP 8447F Option H64Dual PreamplifierThis dual preamplifier improvesreceiver and spectrum analyzersensitivity. It is ideally suited foruse with the HP 11940A and11941A close-field probes todetect low-level emissions from a device under test. Radiatedemission measurements using aspectrum analyzer and antennaare improved by the increasedsensitivity that this unit offers.

HP 11940A and 11941AClose Field ProbesThese hand-held probes arespecially designed to measuremagnetic field radiation fromsurface currents, slots, cables,and ICs for EMC diagnostic andtroubleshooting measurements.Their unique design results in ahigh level of electric field rejection.This significantly reduces errorsallowing calibrated and repeatablemeasurements. Each probe iscalibrated and comes with atwo-meter, RG-223 coaxial cable,an SMA(f) to Type-N(m) adapter,and an SMA(f) to BNC(m) adapter.

HP 85685A RF PreselectorThe HP 85685A RF preselectoris designed to operate with theHP 8566B and 8568B spectrumanalyzers. The RF preselectoradds tracking filters to reduceoverloading from out-of-bandsignal and preamplifiers forimproved system sensitivityover the 20 Hz to 2 GHz frequencyrange. The HP 85685A RFpreselector has two inputs, 20 Hz to 50 MHz and 20 MHz to2 GHz. There is also a bypass modewhich is DC to 18 GHz. Input 1has a built-in transient limiterfor protection from transientsgenerated by line impedencestabilization networks (LISN).
The RF preselector is fullyprogrammable over the HP-IB (IEEE-488).

HP 85650A Quasi-PeakAdapterThe HP 85650A quasi-peakadapter is an accessory usedwith the HP 8566B or 8568Bspectrum analyzers for perform-ing quasi-peak measurementsas recommended by CISPR.These include the correct 6 dBband- widths (200 Hz, 9 kHz,120 kHz) and the specifieddetector charge and dischargetime constants.
The bypass mode returns thespectrum analyzer back tostandard operation unaffectedby the quasi-peak adapter. Inthe normal mode the threeCISPR bandwidths are avail-able and the quasi-peak detectorcan be turned on and off.
There is a built-in speaker andphone jack for monitoringsignals.
The HP 85650A provides nineform C (SPDT) auxilliary switchescan be used with external powersupplies to switch coax relays,DUT power, or your individualswitching needs. Six switchesare multiplexed such that whenone is on five are off.
All functions are controlled overthe HP-IB (IEEE 488) exceptvolume and line.
