R&S FSV-K7/K7S
Manual operation:
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:QFACtor
This command queries the Q factor (quality) of n dB down measurements.
Suffix:
<n>
<m>
Example:
Manual operation:
CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:RESult?
This command queries the distance of the n dB down markers from each other.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweeps.

INIT:CONT OFF
Switches to single sweep mode.
CALC:MARK:FUNC:NDBD ON
Switches on the n dB down function.
INIT;*WAI
Starts a sweep and waits for the end.
CALC:MARK:FUNC:NDBD:QFAC?
Queries the Q factor of the measured bandwidth.

The result depends on the span.
In case of frequency domain measurements, the command
returns the bandwidth between the two n dB down markers in
Hz. In case of time domain measurements, the command
returns the pulse width between the two n dB down markers in
seconds.
INIT:CONT OFF
Switches to single sweep mode.
CALC:MARK:FUNC:NDBD ON
Switches on the n dB down function.
INIT;*WAI
Starts a sweep and waits for the end.
CALC:MARK:FUNC:NDBD:RES?
Outputs the measured value.
