Instrument Functions: M - O
Marker Trace 1, 2, or 3, or Auto. In Auto mode, the analyzer places markers on the
lowest-numbered trace that is in Clear Write mode. If no trace is in Clear Write mode, it
places the marker on the lowest-numbered trace in Max Hold mode. If there are none, then
it uses the lowest-number trace in Min Hold mode, then in View mode. For example, if trace
1 is in view, and trace 2 is in clear write, any new marker is assigned to trace 2.
Key Path: Marker
State Saved: The Marker Trace for each marker is saved in instrument state.
Factory Preset: Auto on, Trace 1
Range: 1 to 3
Remote Command:
:CALCulate:MARKer[1]|2|3|4:TRACe 1|2|3
Puts the marker on the specified trace and turns Auto OFF for that marker.
:CALCulate:MARKer[1]|2|3|4:TRACe?
The query returns the number of the trace on which the marker currently resides, even if
that marker is in Auto mode.
:CALCulate:MARKer[1]|2|3|4:TRACe:AUTO OFF|ON|0|1
Turning Auto off sets the Marker Trace value to the number of the trace on which the
marker currently resides.
:CALCulate:MARKer[1]|2|3|4:TRACe:AUTO?
The response to the query will be 0 if OFF, 1 if ON.
Example: CALC:MARK1:TRAC 2 places marker 1 on trace 2.

This access a menu that enables you to affect how the x-axis information for the selected

of the display. It only affects the readout on the display of the horizontal position
information (for example, frequency).
NOTE It does not affect the way this information is sent remotely in response to the
CALC:MARK:X? command.
