Marker X Axis Position (Remote Command Only)
Sets the marker X-Axis Scale position in trace points. This setting has no effect if the
control mode is Off, but is the SCPI equivalent of entering a value if the control
mode is Normal or Delta - except in trace points rather than X-Axis Scale units. The
entered value is immediately translated into the current X-Axis Scale units for
setting the value of the marker.
Remote
Command
:CALCulate:SPURious:MARKer[1]|2|…|12:X:POSition <real>
:CALCulate:SPURious:MARKer[1]|2|…|12:X:POSition?
Example
:CALC:SPUR:MARK10:X:POS 300
:CALC:SPUR: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 Marker X-Axis Value query returns Not A Number (NAN)
State Saved Saved in instrument state
Min/Max –/+9.9E+37
Marker Y Axis Value (Remote Query only)
Returns the marker Y Axis value in the current marker Y Axis unit.
Remote
Command
:CALCulate:SPURious:MARKer[1]|2|…|12:Y?
Example
:CALC:SPUR:MARK11:Y?
Notes Returns the marker Y-Axis result, if the control mode is Normal or Delta. If the marker is OFF, the
response is Not A Number
In the Complex Spectrum measurement, when the marker is on and Marker Trace is set to IQ, it returns
I and Q values
Case #1 - MarkerTrace SPEC, I or Q: returns a single double value
–
>:CALC:SPEC:MARK1:Y?
–
-2.402406506109E+001
Case #2 - MarkerTrace IQ: returns a double array of two values, the first is I, and the second is Q
–
>:CALC: SPEC:MARK1:Y?
–
-3.006944493834E-003,+9.9870666467354E-004
The IQ selection is for backward compatibility purposes. It is recommended that the users use the I
and/or Q selection instead
