Arbitrary: freezes the marker at the position determined by the current stimulus and
response value. Tracking is disabled. The marker stores the stimulus value and – in
addition – its X and Y coordinates in the current
Marker Format .
The marker can be moved freely inside the diagram, directly adjusting its X and Y coor-
dinates. If in the current trace format the X axis represents the stimulus, the marker's
stimulus value is adjusted accordingly. Otherwise the marker's stimulus value remains
unchanged and is not shown in the
Marker info field . Switching between trace formats
resets the marker position to the response value at the marker's stimulus value, i.e. the
marker snaps to the trace.
Remote command:
CALCulate<Chn>:MARKer<Mk>:TYPE
CALCulate<Chn>:MARKer<Mk>:REFerence:TYPE
Marker Info
Displays the marker coordinates above the marker symbol.
Remote command:

Ref Mkr -> Mkr
Places the reference marker to the position of the active marker. "Ref. Mkr -> Mkr" is
not active if the active marker is a reference marker.
Remote command:

Export Markers
Calls up a "Save As"... dialog to store the current marker values to a marker file.
The analyzer uses a simple ASCII format to export marker values. By default, the
marker file extension is
*.txt
. The file contains all traces in the active channel setup
together with their names and measured quantities. Below each trace, the file shows a
list of all markers with their names, stimulus and response values.
The following example of a marker file describes a channel setup with two traces,
"Trc1" and its memory trace "Mem2[Trc1]". "Trc1" has a reference marker "R" and
three normal markers "M1, M2, M3" assigned, the memory trace has no markers.

10.10.3 Set by Marker tab
The "Set by Marker" functions use the active marker to define the sweep range, scale
the diagram and introduce an electrical length offset. The functions are unavailable if
the active trace contains no markers (e.g. after "All Markers Off").
