Usage: Query only
Manual operation: See "n dB down Delta Value" on page 145
CALCulate:MARKer:FUNCtion:NDBDown:QFACtor?
This command queries the Q factor of n dB down measurements.
Return values:
<QFactor>
Usage: Query only
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. See also INITiate:CONTinuous on page 278.
Return values:
<Distance> 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.
Example:
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.
Usage: Query only
Manual operation: See "n dB down Marker State" on page 145

Parameters:
<State> ON | OFF
*RST: OFF
Example:
CALC:MARK:FUNC:NDBD:STAT ON
