Command
:CALCulate:SEMask:MARKer[1]|2|…|12:X:POSition <real>
:CALCulate:SEMask:MARKer[1]|2|…|12:X:POSition?
Example
:CALC:SEM:MARK10:X:POS 1001
:CALC:SEM:MARK10:X:POS?
Notes The query returns the marker’s absolute X Axis value in trace points if the control mode is Normal, or the
offset from the marker’s reference marker in trace points if the control mode is Delta. The value is
returned as a real number, not an integer, corresponding to the translation from X-Axis Scale units to
trace points . When a Marker is turned on, it is placed center of the screen on the trace. Therefore, the
default value depends on instrument condition. If the marker is Off, the response is Not A Number
Preset After a preset, all markers are turned OFF, so the query returns Not A Number (NAN)
State Saved Saved in instrument state
Min -9.9E+37
Max 9.9E+37
Marker Y Axis Value (Remote Command only)
Returns the marker Y-Axis value in the current marker Y Axis unit.

Command
:CALCulate:SEMask:MARKer[1]|2|…|12:Y?
Example
:CALC:SEM:MARK11:Y?
Notes The query returns the marker Y-Axis result, if the control mode is Normal. If the marker is Off, the
response is Not A Number
Preset Result depends on Markers setup and signal source

Marker Mode
Sets the marker control mode to POSition (Normal) or OFF.
If the selected marker is OFF, pressing Marker sets it to POSition and places it at
the center of the screen, on the trace determined by the Marker Trace rules. At the
same time, Marker X Axis Value appears on the Active Function area. If the current
control mode for the measurement is OFF, there is no active function, and the active
function is turned off.
