CALCulate<1|2>:MARKer<1...4>:FUNCtion:NDBDown:TIME?
This command queries the two time values of the "N dB Down" markers in the specified measurement
window. The suffix <1...4> has no meaning with this command. The two time values are output in
ascending order, separated by commas.
To obtain a valid query response, a complete sweep with synchronization to the sweep end must have
been performed in between activating the function and querying the measurement results. This is
possible only in single-sweep mode.
Example:
"INIT:CONT OFF"
'Switches to single-sweep mode.
"CALC:MARK:FUNC:NDBD ON"
'Switches on the "N dB Down" function in screen A.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK:FUNC:NDBD:TIME?"
'Outputs the time values of the temporary markers in screen A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A-T
This command is a query only and thus has no *RST value
CALCulate<1|2>:MARKer<1...4>:FUNCtion:ZOOM <numeric_value>
The frequency at the marker position becomes the new center frequency at the diagram. The results
of a previous measured scan are displayed in the activated frequency range.
Example:
"INIT:CONT OFF"
'Switches to single-sweep mode
"CALC:MARK:FUNC:ZOOM 1kHz;*WAI"
'Activates zooming in screen A and waits for its end.
for phase noise mode
"CALC1:MARK1:FUNC:ZOOM 10"
'Zooms in around marker 1 by a factor of 10.
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A
This command is an event and therefore has no *RST value and no query.
