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 the SA mode, Offset sub op code
1 is used for both BTS and MS
Couplings Coupled to Start and Stop offset and Meas BW multiplier. This parameter must adhere to the rule (N x
Res BW) <= (Stop freq of the offset - Start freq of the offset), where N is the multiplier. If the multiplier
is changed, the Res BW will change to ensure this. When set manually, Res BW Coupling is set to
manual
The resolution bandwidth is coupled to the offset width determined by the start frequency and stop
frequency
