NORMal: If tracking is enabled (CALCulate<Chn>:
MARKer<Mk>:SEARch:TRACking ON or CALCulate<Chn>:
MARKer<Mk>:REFerence:SEARch:TRACking ON), the mark-
er's stimulus value (CALCulate<Chn>:MARKer<Mk>:X? or
CALCulate<Chn>:MARKer<Mk>:REFerence:X?) is updated
automatically with every sweep, otherwise it is fixed. The marker
position (CALCulate<Chn>:MARKer<Mk>:Y? or
CALCulate<Chn>:MARKer<Mk>:REFerence:Y?) is adjusted
to the corresponding response value, i.e. the marker is always
positioned on the trace.
The marker's stimulus value can be set using
CALCulate<Chn>:MARKer<Mk>:X or
CALCulate<Chn>:MARKer<Mk>:REFerence:X; the marker
automatically follows the trace.
FIXed: freezes the marker at the position determined by the cur-
rent stimulus and response value. The response value stored
with the marker is not adjusted to subsequent sweeps. Tracking
is disabled. Stimulus and response value are stored with the
marker; they are not adjusted to subsequent sweeps and trace
format changes.
The marker stimulus can be set using
CALCulate<Chn>:MARKer<Mk>:X or
CALCulate<Chn>:MARKer<Mk>:REFerence:X, but the
response value remains fixed.
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 (see
CALCulate<Chn>:MARKer<Mk>:FORMat or
CALCulate<Chn>:MARKer<Mk>:REFerence:FORMat).
The marker position can be set using
CALCulate<Chn>:MARKer<Mk>:X and
CALCulate<Chn>:MARKer<Mk>:Y or
CALCulate<Chn>:MARKer<Mk>:REFerence:X and
CALCulate<Chn>:MARKer<Mk>:REFerence:Y. If, in the cur-
rent trace format, the X axis represents the stimulus, the mark-
er's stimulus value is adjusted accordingly. Otherwise the mark-
er's stimulus value remains unchanged. Switching between
trace formats resets the marker position to the response value at
the marker's stimulus value.

Example:
CALC:MARK ON; :CALC:MARK:TYPE FIX
Create marker 1 and display it in the center of the sweep range
as a fixed marker.
CALC:MARK:X 1GHz
Shift the marker horizontally. The response value remains fixed.
