Info BW
Enables you to specify the information bandwidth for the analyzer. This is used to set
the hardware filter of the ADC.

State Saved Saved in instrument state.
Min/Max 1 kHz/The analyzer’s Max Info Bandwidth is dependent on the BW options:
VXT model M9421A:
No Option = 40.0 MHz
Option B40 = 40.0 MHz
