[:SENSe]:AFPanalyzer:IFBW:AUTO?
Title
IF bandwidth coupling
Description:
Sets the state of the coupling of the IF bandwidth to the span. Setting the value to 1 results in the IF bandwidth being coupled to the span. That is, when the span changes, the IF bandwidth changes. Setting the value to 0 results in the IF bandwidth being un-coupled from the span. That is, changing the span does not change the IF bandwidth.
