NEMO FSR1
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
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.

Connecting the Nemo FSR1:
1. Connect an antenna cable to scanner RF input. If you are measuring with two
downconverters, connect an antenna in both RF inputs (see picture below).

Nem o F S R1

2. Connect Ethernet cable(s) to the scanner Ethernet port(s) and to the Nemo Outdoor laptop.
3. Go to Control Panel | Network and Internet | Network and Sharing Center. Click on
Change adapter settings.

4. Right-click on Local Area Connection and select Properties. In the Local Area Connection
Properties dialog, select Internet Protocol Version 4 (TCP/IPv4) and click Properties.

5. Select Use the following IP address and type in an IP address that is different from that of
the scanner. The IP address should be 192.168.3.xxx where the xxx can be anything else
except 250, 251, 252, or 253 because those four IP addresses are reserved for the scanner.
Click OK and Close.

♦

Please note that by default the Nemo FSR1 is delivered with a fixed IP address. The IP
address can be changed with a separate utility software. The following IP addresses are
used in Nemo Outdoor:
•

"Nemo Scanner LAN" = 192.168.3.253

•

"Nemo Scanner LAN 2" = 192.168.3.252

Changing the Nemo FSR1 IP Address
The default address and name settings of the Nemo FSR1 are generally suitable for most
users. However, if you have two or more Nemo FSR1 scanners connected to the same
measurement laptop, you will need to assign a different IP address for each scanner. By
default, the Nemo FSR1 scanners are delivered with a fixed IP address: 192.168.3.253. When
changing the IP address, please use the following IP addresses supported in Nemo Outdoor:
•

"Nemo Scanner LAN" = 192.168.3.253

•

"Nemo Scanner LAN 2" = 192.168.3.252

•

"Nemo Scanner LAN 3" = 192.168.3.251

♦

If a serial port is not available on the computer, a USB-to-serial adapter can be used.
Follow the manufacturer’s instructions for driver installation and use of the adapter. If an
adapter is used, the COM port to choose for the Hyperterminal connection should be the
port assigned by Windows to the USB/serial adapter (see Device Manager, Ports).
Start a terminal port software, such as, HyperTerminal. Select COM1 or the port assigned to the
USB/serial adapter in the Connect using field and click Configure.

The scanner firmware is updated and the scanner is restarted. Check from the scanner
information that the IP address has changed. Now you can close the HyperTerminal.

Connecting a GPS Antenna to Nemo FSR1
For optimum performance of the FSR1, it is strongly recommended to connect the GPS antenna
to the scanner. 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

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.
Preamble delay refers to the number of samples between expected arrival time and actual

Reuse factor refers to a system design parameter that can be manipulated to achieve the
desired balance between the interference and the network coverage. The WiMAX air interface
modulating waveform has been divided into three segments (Segment 0, 1 and 2). The
allocation of frequency sub-carrier into these three segments is done in such a way that e.g. a
downlink signal on segment 0 will not interfere with the downlink signal on segment 1. In a
Reuse Factor 1 measurement, contributions from all the three segments are considered in the
measured parameters, so that the CINRs are calculated from all the three segments. When
Reuse Factor 3 is selected, only the contribution of the desired segment is considered, and the
CINRs are calculated only from the same segment. As a broad guideline, measurements
performed with Reuse Factor 1 will provide the signal quality of the all the detected preambles
relative to each other, whereas the Reuse Factor 3 category of measurements will provide the
signal quality of preambles within the same segment.

PCTEL scanners are connected to the Nemo Invex chassis (UIC module) with a USB cable. If
your PCTEL scanner has a serial cable, you will need a USB serial adapter. The USB cable is
connected to the USB-1 or USB-2 port on the UIC module.

PCTEL scanners can be attached on top of the Nemo Invex chassis with a mounting plate.

To be able to make Top-N preamble scanning the scanner receiver must acquire a GPS fix
at least 30 seconds before starting the Nemo Outdoor application in online mode. If the
existing configuration file includes a PCTEL WiMAX scanner, it is advised to open the
configuration file in offline mode. If scanner does not send any results after 30 seconds,
it is advised to send a reset command to the scanner via the user interface.

MEASURING WITH PCTEL SCANNERS
Frequency Scanning – PCTEL GSM/UMTS Scanners
Frequency scanning can be used to scan band power. It is also useful for checking that the
band is deselected and for finding out the center frequency.
1. After the scanner is connected and activated in Nemo Outdoor, open the Measurement
Properties dialog by selecting Measurement | <device> | General Properties.

Set start and stop frequencies defines the frequency range that will be scanned.
Set center frequency and bandwidth defines the frequency range that will be scanned.
The Sample count field determines the sample count measured for the given frequency range.
5. The Add to Scanning List menu enables you to decide whether the new scanning set is
added to the scanning list, or saved as a predefined set also for later use.
6. The Predefined scanning sets can be used to quickly select the frequency range to be
scanned. Select a set from the list, and click on Add to Scanning List.
With PCTEL EX scanning receivers, the internal frequency range is defined with start
frequency, resolution bandwidth (RBW) and number of points. Stop frequency = start frequency
+ (frequency spacing) * (number of points – 1). All the points need to be within the frequency
range of the requested RF Band. Frequency spacing is between the center frequencies and
spacing between points is half of the resolution bandwidth. The maximum number of samples
(points) is 2560. As seen in the formula above, stop frequency is calculated based on start
frequency and number of points. Stop frequency set by the user is only requested value but it is
not necessarily used during the measurement.

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 make spectrum analyzer measurements. The number of samples
is used only for the frequency range supported by the scanning receiver. Nemo Outdoor does
not read the supported frequency range from the scanning receiver. For example, in the picture
below the user has set start and stop frequencies as seen within the red area. However, the
scanning receiver supports only frequency ranges shown by the green areas. The number of
samples is used only for green areas and the correct RBW is selected accordingly.
