BW. The VBW/RBW Ratio can be set manually or put in to auto mode.
Couplings: When Video BW is set manually, Channel Video BW Mode is set to MANual
Value is coupled with Channel Detector selection, Channel Sweep Time,
Channel Resolution BW.
When set to Auto, the video bandwidth is automatically calculated.
