Marker
Accesses the marker control softkeys to select the
type and number of markers. Markers are
diamond-shaped characters that identify points of
traces. Up to six pairs of markers may appear on
the display simultaneously; only one pair can be
controlled at a time. The marker that is controlled
is called the “active” marker. Pressing [MARKER]
activates the Normal menu key.
Marker
Selects one of the six possible markers. A marker
that has already been selected will become active
when it is turned on. If a marker has been turned
on and assigned to a specific trace, it will become
active on that trace if that marker is selected.
Key access: [MARKER]
Normal
Activates a single frequency marker at the center
of the active trace if a marker is not already
displayed. If a marker is displayed before the
Normal function is enabled, the marker is enabled
at the position of the selected marker. The marker
number is indicated above the marker. The knob
and/or arrow keys move the marker left or right. If
a value is entered from the numeric keypad, the
marker is moved to the trace point nearest to that
value. Annotation in the active function block and
in the upper right corner indicates the frequency
and amplitude of the marker (time and amplitude,
if in zero span.) Pressing Normal turns off the Delta
function and moves the active marker to the delta
marker position.
