For more information on the GPIB Command conventions, see GPIB Command conventions

For the measurement, see Occupied Bandwidth (OBW) Measurement.

FETCh:TOBWidth[:ALL]?

Function

Queries an occupied bandwidth measurement result.

 

This query returns a comma-separated list of values in the following order: integrity indicator, occupied bandwidth, lower frequency, upper frequency.

 

These results can also be queried individually using the

FETCh:TOBWidth:INTegrity?, FETCh:TOBWidth:BANDwidth[:AVERage]?, FETCh:TOBWidth:FREQuency:LOWer?, FETCh:TOBWidth:FREQuency:UPPer? commands.

 

If the multi-measurement state is on, the result represents the average of a number of occupied bandwidth measurements. Multi-measurement state, by default, is off.
