Marker
This hardkey 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 twelve possible markers. If a marker has already
been selected it will become the active marker.

selected trace. The trace selection will search for the lowest
numbered trace in the following mode order:

Marker Trace
Mode Normal
Activates a single frequency marker at the center of the
active trace if not already displayed.
Displaying a marker before enabling the
Normal
function enables
the marker at the position of the selected marker. The marker
number shows above the marker. The knob and/or arrow keys
move the marker left or right. Entering a value from the numeric
keypad moves the marker 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.
