CALCulate<n>:MARKer<m>:FUNCtion:NDBDown:TIME?
This command queries the position of the n dB down markers on the x-axis when
measuring in the time domain.
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:
<TimeX1> absolute position in time of the n dB marker to the left of the ref-
erence marker in seconds
<TimeX2> absolute position in time of the n dB marker to the right of the
reference marker 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:TIME?
Outputs the time values of the temporary markers.
Usage: Query only
Manual operation: See "n dB down Delta Value" on page 145
