MEASURING WITH ANRITSU SCANNERS

Frequency Scanning 1. Open the Measurement Properties dialog by selecting Measurement | | General

Properties.

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

If the scanner supports only one carrier, you can select either GSM or UMTS channels to be scanned.

If the scanner supports two carriers, you can select for scanning both GSM and UMTS channels. If you select GSM channels, you can select a maximum of one UMTS channel. If you do not select GSM channels, you can select one or two UMTS channels.

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

Anri tsu 16

Note that the scanner reports the 32 strongest channels from the selected GSM channels.

Channel style defines the bandwidth of the measured channel. For GSM the options are 200 kHz and 30 kHz narrow.

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.

RX Level Maximum: the data reported is the maximum RX level, in dB, of the number of samples.

RX Level Minimum: the data reported is the minimum RX level, in dB, of the number of samples.

RX Level Standard Deviation: the data reported is the standard of deviation of the number of samples reported as an integer.

RX Level 10%: the data reported is the 10th percentile RX level, in dB, of the number of samples.

RX Level 50%: the data reported is the 50th percentile RX level, in dB, of the number of samples.

Anri tsu 17

RX Level 90%: the data reported is the 90th percentile RX level, in dB, of the Number of samples.

Measurement period defines the time in milliseconds for which the scanner measures and then reports the result.

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

Selecting the BSIC decoding option displays BSIC value in a measurement window.

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

BCCH C/I option is available with PCTEL and Rohde&Schwarz GSM scanners only.

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

Anri tsu 18

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 | | General Properties.

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

Note that some of the options are enabled/disabled in this dialog according to the selected scanner model.

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

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.

Measurement period defines the time in milliseconds for which the scanner measures and then reports the result.

Anri tsu 19

Number of fingers defines the maximum number of fingers used for RAKE in measurement.

Selective level determines a valid path. Set a value (in dB) to decide a valid path from the noise floor (average value).

Rake threshold determines a valid path (in dB). Subtracting the set value from a path with a maximum correlation value gives the lower limit of the valid path.

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.

Delay profile option enables/disables delay profile scanning. The Channel number field provides a list of channels that can be selected for scanning.

Finger option enables and disables Finger measurements for the scanner.

P-SCH defines if the selected scanner will measure the P-SCH Ec/N0 value for each scrambling code.

SIR (signal to interference ratio) defines if the selected scanner will measure the SIR value for each scrambling code.

S-SCH defines if the selected scanner will measure the S-SCH Ec/N0 value for each scrambling code.

The Top-N Configuration button will open the Select Channels dialog where you can select channels for pilot scanning. If you press the arrow, a drop-down menu will appear from where you can select Top-N Search Configuration.

Please note that the Top-N Search Configuration dialog is available for Anritsu UMTS scanners only.

Anri tsu 20

In the Top-N Search Configuration dialog you can limit the search performed by the scanner and consequently speed up the search.

Group specifies the group number for the primary scrambling code in the range of 0 to 63.

Secondary code specifies the secondary scrambling code. Limit range should be set from 0 to 0.

Channelization code specifies the channelization code. Limit range should be set from 0 to 0.

Search method defines how the search is performed. P-CPICH (primary common pilot channel) searches with P-CPICH. SCH performs a three-step search with P-SCH and S-SCH.

To select pilot parameters:

1. Select the TOP-N Mode option.

2. Set the Number of Scrambling codes value. This defines how many strongest pilots are to be reported by the scanner. The maximum is 32 pilots.

Anri tsu 21

To select channels:

1. In the Measurement Properties, Pilot scanning, UMTS page, click the Top-N Configuration button. The Select Channels dialog is opened.

2. The table displays the channel numbers, not the frequencies.

Anri tsu 23

3. Set the Group search range. The group number is the scrambling code divided by 8. For example, SC (scrambling code) 12 = group 1, cell 4.

4. Set the Cell search range. The cell number is the division modulus. For example, SC (scrambling code) 12 = group 1, cell 4.

5. The Secondary Code and the Channelization Code ranges should be set from 0 to 0 for scanning only the P-CPICH.

6. Select the Search Method. SCH means that the P-CPICH are searched using P-SCH and S-SCH. P-CPICH means that the P-CPICH are searched without using P-SCH and S-SCH.

Note that the P-CPICH method is much slower than the SCH method.

7. Click OK to accept the settings and to return to the Measurement Properties dialog.

8. Data processing method defines how the scanner will process samples before reporting.

9. PN threshold defines the limit above which Ec/N0 peaks must go if Aggregated data processing method is used.

In pilot scanning mode, the RSSI is always measured for each channel.

In pilot scanning mode the P-CPICH Ec/N0 and RSCP are always measured for each scrambling code.

10. After making the appropriate settings, click OK and OK again and go to online mode to start the scanning.

11. A green light on the scanner Device Status window should start blinking. This means that the device is working properly and scanning using the default settings. In TOP-N Mode this may take a few seconds.


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 components 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.

Anri tsu 24

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

Pilot Scrambling Code Scanning Pilot Scrambling Code Scanning or Known Scrambling Code Scanning can be used to scan known pilots. The Known Scrambling Code Scanning will from now on be referred to as Normal Pilot Mode.


1. Go to the Measurement Properties, Pilot scanning, UMTS page .

2. Clear the TOP-N mode option and click the Select Channels button. The Select Scrambling Codes dialog is opened.

3. Select channels in the Selected channel numbers table by clicking the Select button.

With the Anritsu ML8720B single carrier scanner only one channel can be selected. If you are measuring with the Anritsu ML8720B-03 dual carrier scanner, two channels can be selected.

4. For each selected channel, select scrambling codes. Select a channel and click the Select button below the Selected scrambling codes table.

Anri tsu 25


6. When using an Anritsu scanner in Pilot Scanning mode, you can define the measurement period. It defines the time period from which results are gathered and processed before reporting.


In Pilot Scanning Mode the RSSI is always measured for each channel.

In Pilot Scanning Mode the P-CPICH Ec/N0 and RSCP are always measured for each scrambling code.




Anri tsu 26

DVB-H Scanning DVB-H scanning can be performed with the Anritsu MS2721B DVB-H Analyzer scanner.


11. In the Measurement Properties, Pilot scanning, DVB-H page, select a frequency to be measured. Anritsu MS2721B DVB-H Analyzer scans frequencies between (DVB-H) 474 - 850 MHz.


13. A green light on the scanner Device Status window should start blinking. This means that the device is working properly and scanning using the default settings.

MEASURING WITH DRT SCANNERS

Frequency Scanning 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 DRT WIMAX scanner is connected and activated in Nemo Outdoor, open the Measurement Properties dialog by selecting Measurement | | General Properties.

2. You can enable or disable the integrated GPS receiver through the Advanced button. It is also possible to use an external GPS device with the scanner.

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

4. In the Channel Style list box, select the channel bandwidth. The options are Wide Band (5000 kHz) and Wide Band 2 (10000 kHz).

DRT 39

5. Click the Select Frequencies button to open the Select Frequencies dialog.

6. The table displays the available frequencies. Select and add them in the Selected view by clicking on Add>>.

7. Remove frequencies from the Selected list by selecting a frequency and clicking the Remove button.

8. Add frequencies in the Selected list by selecting a frequency from the Available list and clicking the Add button.





DRT 40

Pilot Scanning 1. After the DRT WIMAX scanner is connected and activated in Nemo Outdoor, open the

Measurement Properties dialog by selecting Measurement | | General Properties.


Channel style refers to the channel bandwidth.

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.

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.

DRT 41

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.

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.

3. The Top-N Configuration button will open the Select Frequencies dialog where you can select frequencies for scanning. The maximum number of frequencies that can be selected is device specific.

1. After the PCTEL LX/EX scanner is connected and activated in Nemo Outdoor, open the Measurement Properties dialog by selecting Measurement | | General Properties.


PCTEL 78

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).

The available Sampling ratio 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.


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.

PCTEL 79


Delay option enables/disables delay profile scanning. Delay is defined as the measured difference between the expected arrival time (GPS time) and the actual arrival time of the maximum peak above the PN threshold. It is reported in chips.




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 Measurement Properties dialog by selecting Measurement | | General Properties.

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

PCTEL 80

PCTEL 81

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.

PCTEL 82

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.

PCTEL 83

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

9. To remove items from the scanning list, select one or more, and select Remove All | Remove Selected Items. Alternatively, click on Remove All to remove every item from the list.




PCTEL 84

LTE OFDM Scanning OFDM scanning can be used for scanning Reference signal / Sync signals with a PCTEL LTE scanner and Nemo Outdoor.

1. After the PCTEL LTE scanner is connected and activated in Nemo Outdoor, open the Measurement Properties dialog by selecting Measurement | | General Properties.



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.


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.

PCTEL 85


RSSI threshold determines a valid path (in dB). Subtracting the set value from a path with a maximum correlation value gives the lower limit of the valid path.

Top-N option enables/disables Top-N scrambling code scanning. If enabled, scanner will report results from N best cells. Number of cells field indicates the number of best cells you want the scanning to notify you of. Up to 16 sectors are reported with specific cell ID.

CINR option activates/deactivates Carrier to Interference and Noise Ratio measuring. Carrier refers to either reference signal power or sync signal power depending on the selected signal type.

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.

Select the MIMO scanning option to start recording MIMO parameters.

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.

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

The Top-N Configuration button will open the Select Channels where you can select channels for pilot scanning. The maximum number of channels that can be selected is device specific.

PCTEL 86

4. 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.

Note that the available options are device specific.


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.
