[:SENSe]:BANDwidth|BWIDth:VIDeo:AUTO OFF|ON|0|1
[:SENSe]:BANDwidth|BWIDth:VIDeo:AUTO?
Title: Video Bandwidth Coupling
Description: Sets the state of the coupling of the video bandwidth to the resolution
Parameter: OFF|ON|0|1
Parameter Type: <boolean>
Default Value: ON
Front Panel Access: BW, Auto VBW
[:SENSe]:BANDwidth|BWIDth:VIDeo:RATio <number>
[:SENSe]:BANDwidth|BWIDth:VIDeo:RATio?
Title: Video Bandwidth to Resolution Bandwidth Ratio
Description: Sets the ratio of the video bandwidth to the resolution bandwidth for
Parameter: <number>
Default Value: 0.33
Range: 0.00001 to 1
Related Command: :BANDwidth|BWIDth:VIDeo:AUTO
Front Panel Access: BW, RBW/VBW (note that this is the inverse ratio)

bandwidth. Setting the value to ON or 1 will result in the video
bandwidth being coupled to the resolution bandwidth. That is, when the
resolution bandwidth changes, the video bandwidth changes. Setting
the value to OFF or 0 will result in the video bandwidth being
un-coupled from the resolution bandwidth. That is, changing the
resolution bandwidth will not change the video bandwidth. When this
command is issued, the video bandwidth setting itself will not change.
The default value is ON. That is, sending :SENS:BAND:VID:AUTO is
equivalent to sending :SENS:BAND:VID:AUTO ON.
use when the video to resolution bandwidth coupling is enabled. Note
that the front panel interface sets the inverse ratio: the resolution
bandwidth to the video bandwidth which is an integer, i.e., if you send
0.35, the display will show 2 not 2.857.
