Off
Turns off the marker currently selected. Then, the marker information displayed
on the screen and the functions concerning the marker will also be disabled.
Reference Marker
Sets the reference marker for the current marker. By default, the reference marker is
the marker next to it.
Remarks:
Each marker can have another marker to be its reference marker.
If the current marker is a Delta marker, the measurement result of the marker
will be determined by the reference marker.
Any marker cannot take itself to be the reference marker.
Marker Trace
Selects the trace that the current marker marks. It can be Trace1, Trace2, Trace3,
and Trace4. One marker can only mark one trace.
Marker X
Sets the frequency (when frequency-domain data source is selected) or time (when
time data source is selected) of the marker to change the position of the marker on
the trace. Press this key to modify the value to change the position of the marker.
Remarks:
If the marker mode of the specified marker is Position or Fixed, set the X value
of the marker.
If the specified marker mode is Delta, set the X value of the delta marker relative
to the reference marker.
When "Fixed" is selected for the marker mode and "I-Q" or "Constellation" is
selected for the trace format, Marker X is used to determine the data points.
