Sets or queries the state of a marker. Setting a marker to state ON or 1 selects that
marker. Setting a marker which is OFF to state ON or 1 puts it in
Normal mode and places
it at the center of the display. Setting a marker to state OFF or 0 selects that marker and
turns it off. The response to the query will be 0 if OFF, 1 if ON.
Example: CALC:MARK2:STAT ON selects marker 2.
CALC:MARK:STAT ON will not modify a marker that is already on.

marker is off, a single marker is activated at the center of the display. The marker stays on
the trace at the horizontal screen position where it was placed unless Signal Track,ora

Search
) is selected. If you are in a marker pair mode, for example Delta Marker,the
reference marker is turned off. You can then adjust the trace point of the marker.
