The controls on this tab include the Marker active function and a radio button
selection of the marker control mode (Normal, Delta or Off) for the selected marker,
as well as additional functions that help you use markers.
Marker Frequency
Sets the marker X-Axis value in the current marker X-Axis Scale unit. Has no effect if
the control mode is Off, but is the SCPI equivalent of entering an X value if the
control mode is Normal.
Remote
Command
:CALCulate:SEMask:MARKer[1]|2|…|12:X <freq>
:CALCulate:SEMask:MARKer[1]|2|…|12:X?
Example
:CALC:SEM:MARK3:X 1.0 GHz
:CALC:SEM: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 the query returns Not A Number (NAN)

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: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
