Return values:
<Position> <numeric value>
The unit of the return value depends on the measurement mode
and format you have selected.
In the Smith chart, the return value also depends on the marker
format you have selected with CALCulate<n>:MARKer<m>:
MODE.
Example: //Turn on single sweep mode and marker 2
INIT:CONT OFF
CALC:MARK2 ON
//Start a sweep and wait for the end
INIT;*WAI
//Query the position of marker 2
CALC:MARK2:X?
CALC:MARK2:Y?
Usage: Query only
