CONNECTING NEMO FSR1 SCANNER
Nemo FSR1 scanner is powered by 10 to 16 VDC. AC operation for the standalone receiver is
achieved by using the optional AC power supply. The AC power supply is designed to work with
100 - 240VAC 50/60Hz. For other voltages or line frequencies contact Anite for the correct
supply.
The standard AC supply is rated at 130 Watts. Actual power requirements will vary depending
on the number of downconverters installed and the receiver tasking. The maximum power
requirement of the scanner is 50 Watts.
DC operation for the standalone receiver can be achieved by connection to a vehicle 12-volt
system. The following table is provided to budget the system current requirements for various
configurations.
Platform configuration/Module 12 VDC current requirement
Basic system w/ single downconverter 3.0 A
Two downconverter system 3.6 A
The estimates given for the scanner assume maximum utilization of the processing capabilities.

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

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

Nemo FSR1 21
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.

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 23
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

Nemo FSR1 25
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 26
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.
Properties.
2. In the Measurement Properties dialog, go to the Pilot scanning, CDMA page.
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 27
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.
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.

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.
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.

♦ Note that the available options are device specific.
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 ms10307200 sf =⋅= TT

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 32
Number of data points and scanning rates are shown in the table below.

♦ 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

NEMO FSR1 SELF-TEST AND CALIBRATION
The self-test feature of the 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 (nemo.helpdesk@anite.com).

Troubleshooting 45
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.
