Notes Bandwidth sub op code, 1 is for BTS, 2 for MS. Default is BTS
Note that Bandwidth sub op code 2 is supported only in non-SA Modes. In SA Mode, Bandwidth sub op
code 1 is used for both BTS and MS
Couplings When Video BW/Res BW is set manually, Channel VBW/RBW Ratio mode is set to MANual
When set to Auto, the VBW/RBW Ratio is automatically calculated
