VBW:3dB RBW
Selects the ratio between the video bandwidth and the equivalent 3 dB resolution
bandwidth to be used for setting VBW when VBW is in Auto.
VBW:3dB RBW (Auto) selects automatic coupling of the VBW:3 dB RBW ratio to the
optimal value based on other instrument settings. To decouple the ratio, press the
Auto/Man toggle on VBW:3 dB RBW, or simply enter a different value for VBW:3 dB
RBW.
When VBW:3dB RBW is manually selected, it may be returned to the coupled state
by setting the toggle on VBW:3 dB RBW back to Auto. This may also be done by
pressing "Auto Couple" on page 2017 or by performing a Preset.
