Delta Mode
Converts the active marker to a delta marker so that its values are measured and indicated relative to the
reference marker (toggle function). A Δ sign placed in front of the marker line indicates that the marker is
in Delta Mode.
The reference marker itself can not be set to delta mode but must be present when another marker is set
to delta mode. The analyzer takes into account these conditions when Delta Mode is selected:
 If Delta Mode is selected while the reference marker is active, the marker in the info list after the
reference marker is activated and set to delta mode. If the current trace contains the reference
marker only, a new M 1 is created and set to delta mode.
 If Delta Mode is selected for a normal marker while the current trace contains no reference
marker, a reference marker is created.
A delta marker is required to set the sweep span using marker functions (Span = Marker).
Remote control:
CALCulate<Chn>:MARKer<Mk>:DELTa[:STATe] ON
Ref. Marker -> Marker
Places the reference marker to the position of the active marker. Ref. Marker -> Marker is not active if the
active marker is a reference marker.
Remote control:
–
All Markers Off
Removes all markers from the active trace. Markers on other traces are not affected. The removed
markers remember their properties (stimulus value, format, delta mode, number) when they are restored.
The marker properties are definitely lost when the associated trace is deleted.
Remote control:
CALCulate<Chn>:MARKer<Mk>:AOFF
Coupled Markers
Couples the markers of all traces in the active setup to the markers of the active trace (toggle function).
While marker coupling is active, the active trace markers assume the role of master markers; the other
markers behave as slave markers, following any change of position of the master marker.
Effects of marker coupling
The concept of marker coupling means that corresponding markers on different traces (i.e. markers with
