control mode is Normal or Delta.
Remote
Command
:CALCulate:CHPower:MARKer[1]|2|…|12:X <freq>
:CALCulate:CHPower:MARKer[1]|2|…|12:X?
Example
:CALC:CHP:MARK3:X 0
:CALC:CHP:MARK3:X?
Notes If no suffix is sent, uses the fundamental units for the current marker X Axis Scale. If a suffix is sent that
does not match the current marker X Axis Scale unit, an error “Invalid suffix” is generated
The query returns the marker’s absolute X Axis value if the control mode is Normal, or the offset from
the marker’s reference marker if the control mode is Delta. The query is returned in the fundamental
units for the current marker X Axis scale: Hz for Frequency and Inverse Time, seconds for Period and
Time
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
Annotation Mkr # <X value> and <Marker value> upper right on graph
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:CHPower:MARKer[1]|2|…|12:X:POSition <real>
:CALCulate:CHPower:MARKer[1]|2|…|12:X:POSition?
Example
:CALC:CHP:MARK10:X:POS 0
:CALC:CHP: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 at the 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/Max –/+9.9E+37
Marker Y Axis Value (Remote Query only)
Returns the marker Y Axis value in the current marker Y-Axis unit.
