• When the user selects the ‘In-Band’ operation mode the scanner calculates the
frequency offset from the channel raster as shown in the second column of Table 1.
• 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 inserts +7.5 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.
