"Default" means that the marker is formatted according to the related trace's
, if the transformation between trace format and marker for-
mat requires a concrete stimulus value, some result values in the marker info field can
be unavailable. Those values are displayed as a sequence of dashes (------).
Remote command:
CALCulate<Chn>:MARKer<Mk>:FORMat
CALCulate<Chn>:MARKer<Mk>:REFerence:FORMat
Marker Style
Defines how the selected marker is displayed on the screen.
Remote command:
n/a
Discrete
Discrete mode means that a marker can be set to discrete sweep points only. If dis-
crete mode is switched off, the marker can be positioned on any point of the trace, and
its response values are obtained by interpolation.
Remote command:
CALCulate<Chn>:MARKer<Mk>:MODE
CALCulate<Chn>:MARKer<Mk>:REFerence:MODE
Marker Mode
Determines if and how the marker's position is adjusted and if and how it can be
moved in the diagram area.
Normal:
is enabled, the marker's stimulus value is updated automatically
with every sweep, otherwise it is constant. The marker position is adjusted to the corre-
sponding response value, i.e. the marker is always positioned on the trace.
If in the current trace format the X axis represents the stimulus, the marker can be
moved horizontally. At the same time, the marker's stimulus and response values are
adjusted, i.e. its vertical position automatically follows the trace.
Fixed:
freezes the marker at the position determined by the current stimulus and
response value. Tracking is disabled. The stimulus and response values are stored
with the marker; they are not adjusted to subsequent sweeps or trace format changes.
If in the current trace format the X axis represents the stimulus, the marker can be
moved horizontally. Moving the marker adjusts the markers's stimulus value, but its
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
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
. 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.
