Marker
Hardkey accesses the marker control softkey menus to select
the type and number of markers. Markers are shown on the
display as diamond- shaped characters that identify points of
traces. Up to twelve pairs of markers (when using Delta Pair
markers) may appear on the display simultaneously; only
one pair can be controlled at a time.
Select Marker Selects one of the twelve possible markers. If a marker has
already been selected it will become the active marker.
Key access:
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.
Key access:
Delta Accesses the submenu to use the marker delta function.

On Off
Delta (On) activates a second marker at the
position of the first marker. If no marker is
present, two markers with the same
identification number will appear at the center
of the display. The marker number is indicated
above the delta marker, and the same number is
indicated with an R (for example, 1R) above the
reference marker. The amplitude and frequency
(or time) of the first marker is fixed.
