CONNECTING DEVICES

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.

6. The device is now connected to the computer. See Starting Devices below for information on

how to connect the scanner with Nemo Outdoor.

System Priority Order with R&S TSMW Scanners

Multiple cellular technologies (systems) are measured in a parallel manner. The different

systems are arranged in a priority order as shown in Figure 4. The CDMA and EVDO systems

are counted as one system. Nemo Outdoor handles priority and allocates the RF ports

automatically. In this case priority refers to the order in which systems are allocated to RF port

#1 and RF port #2. The resource slot number defines in how many processes one RF port is

divided.

Both ports, RF #1 and RF #2, have 100% of available resources. When only one system

(except LTE) is measured, for example WCDMA, it is set to be measured via RF port #1 with

100% of its resources. When two systems are measured simultaneously, for example GSM and

WCDMA, GSM has higher priority over WCDMA. GSM is set to be measured via RF port #1

with 100% of its resources, whereas WCDMA system is set to be measured via RF port #2 with

100% of its resources.


When three systems are measured simultaneously, for example GSM, WCDMA and CDMA, the

systems are again allocated in the priority order for the two RF ports. In this case RF port #1 is

shared by two systems: GSM and CDMA. Each system gets 50% of the RF port #1 resources.

100% of RF port #2 resources are allocated to WCDMA measurements.

With LTE, individual carriers are allocated to the two RF ports. For example, when measuring

two or more LTE carriers, carriers are arranged in order from lowest frequency number to the

highest. After that, carriers (frequencies) are allocated to the RF ports so that the first carrier is

allocated to RF port #1 and the second carrier to RF port #2, third carrier is again allocated to

RF port #1 and the fourth carrier to RF port #2, etc.

If the measurement setup includes an odd number of other systems in addition to LTE, the first

LTE carrier is allocated to RF port #2. The second LTE carrier is allocated to RF port #1, etc.

However, if the measurement setup includes only one other system in addition to LTE, the other

system is allocated to RF port #1 and all LTE carriers are allocated to RF port #2.

Spectrum scanning is counted as one of the systems. Spectrum scanning always has the

highest priority and it is set to be measured via RF port #1. The resource slot number defines in

how many processes one RF port is divided.

1. After the PCTEL LX/EX scanner is connected and activated in Nemo Outdoor, open the


Properties.





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





Pilot window mode defines the position of the chips that are searched for pilot across in regard

to the ideal pilot position (0 chip delay for a given pilot).

Sampling ratio option is available for PCTEL EX scanners only. The available options are 1:1,

1:2, 1:4 and 1:8. With ratio 1:1 all samples (Pilotscan events) are logged, with ratio 1:2 every

second sample is logged, with ratio 1:4 every 4th sample is logged, and with ratio 1:8 every 8th

sample is logged. By decreasing the sampling ratio you can decrease the output file size, but

the scanning accuracy will be diminished.

Spectrum Scanning

Spectrum scanning is enabled on PCTEL EX scanners only in online mode. Hence, the

device needs to be added to Nemo Outdoor in online mode to activate the Spectrum

scanning functionality

1. After the PCTEL EX scanner is connected and activated in Nemo Outdoor, open the


Properties.



3. Select the Enable spectrum scanning option, and click Add.

4. To create new scanning sets, define the scanning frequencies in the Reporting view.

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.

7. Click OK to return to the Spectrum scanning page.


8. The added frequency ranges will be added to the Scanning list.

aggregate method, the sum of all peak pilot Ec/Io values above the PN threshold is calculated.

Top-N option enables/disables TOP-N scrambling code scanning. If enabled, scanner will report

results from N best preambles. Number of preambles field defines how many preambles are

reported by the scanner in TOP-N mode.

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

arrival time of preamble with respect to GPS time reference. The values range from 0 to

1023+32. Each sample corresponds to 89.285 nanoseconds.


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.

4. To create new scanning sets, define the scanning frequencies in the Reporting view.

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.

With Rohde & Schwarz scanner receivers, the user can set the start and stop frequency

between 80MHz and 3000MHz. Sample counts are divided to the frequency range defined by

the user. The TSMx device has a native frequency resolution of 12.8 KHz. It should be noted

that the frequency shift cannot be lower than 12.8kHz, which sets the number of sample count

max. limit to 5000 samples. In case the selected frequency range and sample count require a

frequency shift lower than 12.8kHz, the sample count is automatically decreased. The sweep

speed, resolution bandwidth and sampling rate are fixed. The sweep speed is 1 GHz / 0.1 sec,

the resolution bandwidth is fixed at 30 kHz.

For example, if the start frequency is 80 MHz, and the stop frequency is 100 MHz, the total

measured bandwidth is 20 MHz. If the sample count is set to 20, power (RMS) is measured

from a 1 MHz bandwidth. With the frequency shift of 12.8 KHz ~ 78 samples are taken from

each 1 MHz bandwidth.


The Add to scanning list menu enables you to decide whether the newly created scanning set

is added to the scanning list, or saved as a predefined set also for later use.
