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
.
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.
P-SCH
defines if the selected scanner will measure the P-SCH Ec/N
0
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/N
0
value for each scrambling
code.

To select channels:
1. In the
Measurement Properties, Pilot scanning, UMTS
page, click the
Top-N
Configuration
button. The
Select Channels
dialog is opened.
♦
The table displays the channel numbers, not the frequencies. If you know the frequency
but not the channel number, the channel number can be calculated by multiplying the
frequency in MHz by five. The channel spacing is always 200 kHz.
2. Remove channels from the
Selected
list by selecting a channel and clicking the
Remove
button.
3. Add channels to the
Selected
list by selecting a channel from the
Available
list and clicking
the
Add
button.
♦
With a PCTEL LX scanner a maximum of 8 channels can be selected in the pilot mode.
♦
With a PCTEL EX scanner a maximum of 15 channels can be selected in the pilot mode.
♦
With a PCTEL MX scanner 1 channel can be selected in the pilot mode.
♦
With a PCTEL LTE EX scanner a maximum of 15 channels can be selected in the pilot mode.
♦
With a PCTEL PCT scanner a maximum of 4 channels can be selected in the pilot mode.
4. Click
OK
to return to the
Measurement Properties
dialog.

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.
♦
Note that with the PCTEL PCT Scanner the maximum number of pilots to be selected for
scanning is 8.
