:CALCulate:<measurement>:MARKer[1]|2|3|4:X:POSition?
Position the designated marker on its assigned trace at the specified X
position. A trace is composed of a variable number of measurement
points. This number changes depending on the current measurement
conditions. The current number of points must be identified before
using this command to place the marker at a specific location.
The marker must have already been assigned to a trace. Use
:CALCulate:<measurement>:MARKer[1]|2|3|4:TRACe to assign a
marker to a particular trace.
The query returns the current X position for the designated marker.
The measurement must be completed before querying the marker.
Example: CALC:SPEC:MARK:X:POS 500
Range: 0 to a maximum of (3 to 920,000)
