CONNECTING A GPS ANTENNA TO NEMO FSR1 For the optimum performance of the FSR1, it is required to connect the GPS antenna to the scanner when using the scanner’s internal GPS. The scanner takes advantage of GPS for timing information which improves the performance of the signal processing algorithms.

Also note for CDMA/EVDO the scanner must have GPS coverage. If CDMA/EVDO in-building testing is to be conducted, the scanner should operate at least 30 minutes in GPS coverage before the antenna is disconnected and then every hour or two of walk testing have an additional 20 minutes in GPS coverage.

The following GPS antenna is delivered with the Nemo FSR1:

• Mighty Mouse III

• 28dB gain low noise amplifier

• Maximum of 6mA current consumption (all voltages)

• 2.5V to 5.5V DC

• Connector: SMA male

Nemo FSR1 13

Connect the GPS antenna cable to the GPS connector in the scanner front panel, add the scanner to Nemo Outdoor and enable the internal GPS (Measurement Properties | General | Advanced).

In order to store GPS data using the internal GPS of Nemo Invex, you need to define a measurement server (UIC) for the scanner. In the Add New Device dialog, select the UIC in the field at the bottom of the dialog. In this case, there is no need to enable the internal GPS of the scanner.

If you prefer using the scanner as a local device with Nemo Invex (i.e., not connected to a UIC), GPS data will not be available unless you enable the internal GPS (Measurement Properties | General | Advanced).

MEASURING WITH NEMO FSR1 SCANNER

FREQUENCY SCANNING 1. Open the Measurement Properties dialog by selecting Measurement | <device> | General

Properties.

2. In the Measurement Properties dialog you can select the channels to be scanned.

3. On the Frequency scanning, GSM page, click the Select Channels button to select the GSM channels to be scanned.

Channel style defines the style of the measured channel.

Data mode defines the type of measurement data computed from each sample. Note that the available selection depends on the scanner type.

• RX Level Average: the data reported is the average RX level, in dB, of the number of samples.

Nemo FSR1 20

Measurement period defines the time in milliseconds for which the scanner measures and then reports the result. Lengthening the measurement period does not change the time period over which raw samples are averaged for a measurement result. If the report time is smaller than the needed averaging time, the measurements will be reported as fast as they can be delivered, but not more often than the averaging time. If the report time is longer than the needed averaging time, pauses between measurements will be introduced so that measurements are reported at the rate requested by the user.

Sample size defines the number of samples taken from each channel before a measurement result is written to file.

Selecting the BSIC decoding option enables BSIC values and co-channel C/I measurements.

BSIC threshold defines the minimum BSIC level that the scanner reports.

Select the BCCH C/I option to activate BCCH decoding. Co-channel C/I is also enabled.

Cell information decoding. Mobile Network Code, Mobile Country Code and Cell ID information can be decoded from BCCH messages.

When the System information decoding option is selected, L3 messages are written in the log file.

4. Click the Start Recording button to start recording the results in an output file.

Nemo FSR1 21

TOP-N PILOT SCANNING - UMTS Unknown Pilot scanning can be used for scanning unknown pilots or the strongest pilots. The Unknown Pilot Scan will from now on be referred to as TOP-N pilot mode/scanning.

∇ To set pilot scanning settings:

1. Open the Measurement Properties dialog by selecting Measurement | <device> | General Properties.

2. In the Measurement Properties dialog, go to the Pilot scanning page.

CPICH Ec/No threshold defines the minimum level for the CPICH Ec/No. If the values are below the threshold, the pilots are not reported.

Channel style refers to the style of the channel. For UMTS scanners, the options are Narrow Band (200kHz) and Wide Band (3.84MHz).

Data processing method defines how the scanned data is processed by the scanner. In aggregate method, the sum of all peak pilot Ec/Io values above the PN threshold is calculated. If there are no peaks above the PN threshold, value -30 dB is returned for WCDMA.

Nemo FSR1 22


Pilot measurement mode defines the measurement mode for pilot scanning.

• In High speed mode scanning speed is higher but sensitivity is lower. In high speed mode, weak pilots may be undetected.

• In High dynamic range mode scanning speed is lower but sensitivity is higher.

Top-N option enables/disables Top-N scrambling code scanning. If enabled, scanner will report results from N best scrambling codes. Number of pilots field defines how many pilots are reported by scanner in Top-N mode. The maximum number is 32.

Cell information decoding. Mobile Network Code, Mobile Country Code and Cell ID information can be decoded from BCCH messages. Note that this is only enabled in online mode and if the option has been purchased with the scanner.

Delay spread defines if the selected scanner will also measure the delay spread value (in chips) for each scanned scrambling code. Delay spread is determined as the difference between the last and first component to break the threshold set in PN Threshold.

When the Neighbor list decoding option is selected, the NLIST (neighbor list) event is written in the log file for WCDMA.

Nemo FSR1 24

Data Processing Method – Peak vs Aggregate If the multipath components are significantly lower than the peak, their contribution will be negligible and the aggregate will be the same as the peak. However, if one or more multipath components are close to the peak component in power, its power combined with the peak component’s power will be larger than either of them alone. In the case where a multipath component is the same strength as the peak the aggregate will be twice the power, or 3dB higher than the peak. Thus, the aggregate will always be the same as or larger than the peak.

As a practical matter, many multipath components are typically present in an urban environment, where there are many surfaces (e.g., buildings) which can reflect the radio signal. By contrast, there may be few or no multipath components in a rural environment.

The difference between Aggregate and Peak is variable. Probably the difference will lie in the range of 0 to 4 dB. If the multipath components are small, they will have no contribution and aggregate will be equal to peak (0 dB difference). In the case above where one multipath is equal to the peak, the doubling of power gives +3dB to the aggregate. There might be cases where two components are the same strength as the peak and this would result in an aggregate +4.7dB relative to the peak. Naturally, if another component becomes higher than the “peak”, it becomes the new peak.

Aggregation does not happen over time, but over multipath components that are all simultaneously present.

Nemo FSR1 25

TOP-N PILOT SCANNING - CDMA/EVDO ♦ Note that the EVDO measurements can only be performed in a proper way when a

CDMA2000 channel is measured as well. In this way, the time relationship between the different PN offsets is resolved.


2. In the Measurement Properties dialog, go to the Pilot scanning, CDMA page.

Channel style refers to the style of the channel. For UMTS scanners, the options are Narrow Band (200kHz) and Wide Band (3.84MHz).

Correlator affects how the scanner works. Bigger correlator size enables the scanner to detect and measure pilot channels with better dynamic but makes scanning speed slower. For example, when using correlator size 2048 versus 512, the dynamic range for pilot measurement changes from –21db to –17db.


Nemo FSR1 26

Pilot Ec/I0 threshold defines the threshold level for the pilot Ec/I0. If the values are below the threshold, the pilots are not scanned.

Pilot increment defines an increment value that the pilot numbers use. If the increment is 4, the valid pilot numbers are 0, 4, 8, etc. The handler uses this configuration value to modify incorrect pilot numbers detected by the scanner, usually off by one which is caused by a multipath signal or a long distance to the BTS.

Top-N mode option enables/disables TOP-N scrambling code scanning. Number of pilots field defines how many pilots are reported by the scanner in TOP-N mode.

The Top-N Configuration button will open the Select Channels dialog where you can select channels for pilot scanning.

♦ Note that the Nemo FSR1 scanner supports a max of 90 cell IDs.




Nemo FSR1 27

TOP-N PILOT SCANNING – LTE 1. Open the Measurement Properties dialog by selecting Measurement | <device> | General

Properties.

2. Go to the Pilot scanning, LTE page to define LTE-specific pilot scanning settings.



CINR refers to the Carrier to Interference and Noise ratio value, in dB *100 (e.g., -16.34). It is based on the requested reuse factor.

Time offset refers to the number of samples between P-SCH Primary Synchronization Signal arrival time with respect to receiver frequency reference that is derived from GPS reference time.

Delay spread defines if the selected scanner will also measure the delay spread value (in chips) for each scanned scrambling code. Delay spread is determined as the difference between the last and first component to break the threshold set in PN Threshold.

Nemo FSR1 28

Sync signal refers to the ratio between the synchronization channel, i.e., primary and secondary signal received power and the interference and noise from the same synchronization signal set.

Reference signal refers to the ratio between the reference signal received power (RSRP) and the interference and noise from the same reference signal set.


The Select Channels button will open the Select Channels dialog where you can select channels for pilot scanning.

When you select LTE channels, you can also define some channel-specific settings. In the LTE Channel Specific Settings dialog, select the channel from the Selected channels list and define the settings.

Channel style refers to the bandwidth of the channel. Supported in Nemo FSR1 firmware 4.0 onwards.

Cyclic prefix defines the type of signal the scanner is set to measure. With Autodetect selected, the scanner will automatically detect the appropriate signal type. If Cyclic Prefix is known to be Normal (most common), setting the scanner to Normal will increase scanning speed slightly.

Uplink-downlink configuration refers to LTE TDD frame structure.

Frame structure type 2 is applicable to TDD. Each radio frame of length ms 10307200 sf =⋅= TT consists of two half-frames of length ms 5153600 s =⋅T each. Each half-frame consists of five subframes of length ms 107203 s =⋅T . The supported uplink-downlink configurations are listed in the table below where, for each subframe in a radio frame, “D” denotes the subframe is reserved for downlink transmissions, “U” denotes the subframe is reserved for uplink transmissions and “S” denotes a special subframe with the three fields DwPTS, GP and UpPTS.

SPECTRUM ANALYZER MEASUREMENTS Spectrum analyzer measurements are supported with Nemo FSR1 scanners. Please note that the scanning receiver must include the Spectrum Analyzer Option (315022-04) to be able to support these measurements. Depending on the RF front ends (down converters), spectrum analyzer measurements can be done for DL or for both DL and UL directions. The frequency range available for spectrum analyzer measurements also depends on the physical RF front ends.

Spectrum analyzer measurements can be done simultaneously either with frequency scanning, pilot scanning or with all modes. Nemo FSR1 scanner does not use any priority orders between different measurement modes. With Nemo FSR1 scanner up to 32 scanning frequency sets can be selected simultaneously.

The user can set the start and stop frequencies or center frequency with bandwidth and sample count via the Nemo Outdoor user interface. If the requested frequency range is not supported by the device, Nemo Outdoor automatically adjusts the frequency range for the device, and only frequency ranges supported by the scanning receiver are used to perform spectrum analyzer measurements.

The number of samples is used only for the frequency range supported by the scanning receiver. With the Nemo FSR1 scanner, the maximum number of samples (points) is 2000. Minimum frequency resolution is 3,75MHz. Nemo Outdoor does not read the supported frequency range from the scanning receiver. For example, in the picture below the user has set the start and stop frequencies as defined within the red area. However, the scanning receiver supports only frequency ranges within the green areas below. The number of samples is used only for green areas and the correct RBW is selected accordingly. It should be noted that the center frequency and bandwidth are always written to the measurement file as set by the user, even if the selected center frequency is not supported by the scanning receiver. In case the defined frequency range is not supported at all by the scanner, no values are reported.

Nemo FSR1 31

Number of data points and scanning rates are shown in the table below.

∇ Performing spectrum scanning


2. In the Measurement Properties dialog, go to the Spectrum scanning page. Select the Enable spectrum scanning option and click on Add.

4. Select Set center frequency and bandwidth to define the center frequency and the bandwidth to be measured. If you manually define the center frequency and bandwidth, you can either select to add them to the scanning list, or save them as a predefined set. Select your option in the Add to scanning list menu.

♦ If the requested frequency range is not supported by the device, Nemo Outdoor automatically adjusts the frequency range for the device, and only frequency ranges supported by the scanning receiver are used to perform spectrum analyzer measurements.

♦ Based on the start and stop frequency and the number of samples (points), Nemo Outdoor calculates the correct resolution bandwidth (RBW). It should be noted that resolution bandwidths with Nemo FSR1 scanners are fixed. The currently supported values are: 1875, 3750, 7500, 15000, 30000, 60000 and 120000 Hz. Nemo Outdoor automatically selects the closest RBW to be used. For example, if the calculated RBW were to be 4000 kHz, RBW 3750 kHz would be selected for use. The used RBW value can be seen in the measurement file.

Nemo FSR1 33

5. You can add scanning sets in the Predefined scanning sets field through the Add to Scanning List button. Click the arrow in the button and select Save as Predefined Set. Define a name in the Enter Frequency Set Name field and click OK.

NEMO FSR1 SELF-TEST AND CALIBRATION

SELF-TEST The self-test feature of the Nemo FSR1 scanner is a method of verifying end-to-end functionality of the scanner. A small, known signal is self-generated and introduced into the scanner input. The measured result must fall within prescribed limits or the self-test fails.

Self-test runs every time the handler is started and notifications are sent to the user interface depending on the calibration results. Self-test results can be viewed in the Nemo Outdoor Output window.

• Test passed

• No action required. Indicates that there are no known issues with receiver/down converter module calibration.

• Calibration warning

• Measured noise level indicates that the down converter is functioning but may be at or approaching calibration limits. Recommended that the down converter is calibrated as soon as possible. Please contact Nemo helpdesk or local sales representative to arrange re-calibration.

• Test failure

• Measured noise levels are significantly out of range and down converter is not functioning correctly. Recommended that the down converter be returned immediately for factory assessment, potential repair, and calibration. Please contact Nemo helpdesk or local sales representative to arrange service for the unit.

Because the self-test feature tests most functions of the scanner, a failure or warning from the self-test can be caused by components of the front-end or the base unit. While in the field, the following tests are recommended to help narrow down the search for the root cause:

1. Power-cycle the Nemo FSR1 scanner (turn it off for 5 seconds, then back on). See if the problem remains.

2. Try the front-end in the other slot of the same scanner base. If the self-test passes with the front-end in one slot of the scanner but fails in the other slot, the scanner base unit is the possible cause of problems.

3. If possible, try the front-end in a different scanner base unit. If the self-test still fails, the front-end is the most likely source of the failure. If the receiver passes in another scanner, the first scanner base unit is likely the cause of the failure.

4. If the base unit is suspect, it should be tested with another front-end installed. If the self-test still reports a failure, the base unit is most likely the source of failure.

If the return of the equipment is planned, both the scanner base and front-end should be returned together for troubleshooting and repair. Log the MAC address and serial number of the base unit and serial number of the front-end and obtain return authorization from Nemo Helpdesk ([email protected]).

CALIBRATION All Nemo FSR1 down converters are calibrated by Anite prior delivery. The first re-calibration of a down converter is 14 months from the initial calibration. Anite recommends re-calibrating down converters annually. The calibration date reminder in Nemo Outdoor/Invex helps arranging the re-calibration. Calibration expiration date information is programmed to each down converter. The Nemo FSR1 handler reads the calibration expiration date information from the scanner and generates calibration expiration notifications for the user interface. Notification is displayed once per day when the following number of days to the expiration date is remaining: 60, 30, 15, 7, 6, 5, 4, 3, 2, 1. On the expiration day and every day after that, the notification is shown every time a measurement is started.

TROUBLESHOOTING

If a Scanner synchronization failed error message appears in the Output window, the scanner is working properly, but the scanner did not find strong enough a CPICH in a short time period. Nevertheless, the measurement will go on normally.

If a Scanner GPS locking failed error message appears in the Output window, the scanner is working properly, but the scanner GPS has no fix or is not connected. The measurement will go on normally, but the scanner accuracy is not as good as it is when the scanner GPS has a fix.

If the Nemo FSR1 license information cannot be read by Nemo Outdoor, please check that the down converter is attached properly. If this does not help, it is possible that the down converter is damaged. Please contact Anite technical support for further advice.
