To improve on the accuracy of radio propagation models, High Speed Mode makes it possible to acquire more samples (max 32 pilots per channel), while High Dynamic Mode offers fewer samples (max 16 pilots per channel) with a larger dynamic range.

Data Processing Method defines how the scanned data is processed by the scanner.

CPICH Ec/N0 Threshold defines the power that is included to find delay spread.

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

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.

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


Delay profile defines from which scrambling code or channel the delay profile is measured.

Timeslot scan check box enables or disables timeslot scanning. If enabled, scanner will scan UMTS timeslots (2560 chips) and report the P-SCH Ec/N0 value per chip. Compression ratio option allows the user to reduce the data generated by scanner when performing timeslot scan. If Compression Ratio is set to 1, there will be 2560 P-SCH Ec/N0 results per timeslot (e.g., for every chip) and if Compression Ratio is set to 4, there will be 640 results (e.g., results for every fourth chip) that are averaged over four chips.

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

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

Time of arrival defines if the selected scanner will measure the time of arrival for each scrambling code. The time of arrival value is relative to GPS time and is measured in chips.

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.


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

Finger check box enables and disables Finger measurements for the scanner.

SIB decoding option is available for Anritsu and PCTEL EX scanners. When the option is selected, SIB messages are written in the log file. Note that when SIB decoding is selected and more than one WCDMA carriers are scanned, it will affect the scanning of other carriers.

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

When the Missing neighbor detection option is selected, the missing neighbor information event (NMISS) is written in the log file. You can view the missing neighbor information, for example, in a grid view.

Uplink interference check box enables and disables uplink interference decoding for the scanner. Available for scanners that support BCH demodulation.

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

♦ Note that the WCDMA EX Scanner only supports TOP-N mode with a max. of pilots.

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

Cell specifies the cell number for the primary scrambling code in the range of 0 to 7.


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.

Preamble CINR: Carrier to Interference and Noise ratio value, in dB *100. (e.g., -16.34). It is based on the requested Reuse Factor.

Reuse factor: 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.

Preamble delay: Number of samples between expected arrival time and actual arrival time of preamble with respect to GPS time reference. The value ranges from 0 to 1023+32. Each sample corresponds to 89.285 nanoseconds.

6. Click OK to exit the dialogs. You are now ready to start measurements. Click the Work Offline/Online button to start the measurement.
