Video BW
Sets the video bandwidth used to calculate the power in the reference channel. The
Channel Video BW can be set manually or put into Auto mode.

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 If Video BW is set manually, Channel Video BW mode is set to MANual
Coupled with Channel Detector selection, Channel Sweep Time and Channel Resolution BW
When set to Auto, the video bandwidth is automatically calculated
