When the user selects the ‘Guard-band’ mode the scanner needs additional
information to calculate the frequency offset since there is a +/-7.5 kHz ambiguity as
shown in column 3 of Table 2. In this mode the user has three choices for ‘frequency
offset’:
o
‘0’: The scanner automatically calculates the offset based on the table. In case
of +/- 7.5 kHz ambiguity the scanner defaults to -7.5 kHz. In that case other
modes should be used. See below.
o
‘1’: The scanner i7.5 kHz offset for the channel raster.
o
‘2’: The scanner inserts -7.5 kHz offset for the channel raster.
•
The scanner provides RP, RQ, CINR, Time offset values for primary and secondary
synchronization channels as well as reference signal.

In order to monitor the standard LTE network, the user can initiate a separate eTOPN
LTE measurement.
