<m> Marker
Parameters:
<Position> <numeric value>
The unit depends on the measurement and marker input mode.
Hz for measurements in the frequency domain.
s for measurements in the time domain.
No unit for channel input mode (CALCulate<n>:MARKer<m>:
FREQuency:MODE).
Example: //Set the delta marker at a distance of 5 kHz to the reference
position.
CALC:DELT3:X:REL 5 kHz
CALCulate<n>:DELTamarker<m>:Y?
This command queries the position of a delta marker on the y-axis.
The result is always a relative value in relation to marker 1.
If necessary, the corresponding delta marker is activated first.
To get a valid result, you have to perform a complete sweep with synchronization to the
sweep end between activating the delta marker and reading out the result. This is only
possible in single sweep mode.

Return values:
<Position> In spectrum analyzer mode, the unit depends on the unit you
have set and the scaling of the vertical axis.
• dB (lin/log) for units DBM | DBPW | DBUV | DBMV | DBUA
• dB (lin), % (log) for units WATT | VOLT | AMPere
Example: //Turn on single sweep mode and delta marker 2
INIT:CONT OFF
CALC:DELT2 ON
//Start a sweep and wait for its end
INIT;*WAI
//Query the position of delta marker 2
CALC:DELT2:X?
CALC:DELT2:Y?
Usage: Query only
