Stop Freq
Specifies the stop frequency for the currently selected offset.
When sending the remote command, missing values are not permitted; that is, if you
want to change values 2 and 6, you must send all values up to 6. Subsequent values
will remain unchanged. The query for this parameter returns 14 values for WLAN
mode, 12 values for other modes.

Notes Comma separated list of values
OFFSet1 is for BTS, 2 for MS. Default is BTS
Note that Offset sub op code 2 is supported only in non-SA Modes. In SA Mode, Offset sub op code 1 is
used for both BTS and MS
If the offset is outside of the frequency range, the result spectrum will be invalid
Couplings Coupled to Start Freq. When Stop Freq goes below Start Freq, Start Freq is automatically adjusted to
Stop Freq minus 100 Hz
