Key Reference 4
N9320A Spectrum Analyzer 93
Marker
Accesses the marker control softkeys that select the type and
number of markers. Markers are diamond- shaped characters
that identify points of traces. Up to twelve pairs of 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. A marker that
has already been selected will become active. If a marker has
been turned on and assigned to a specific trace, it will be
active on that trace when selected.
Key access:
Normal Activates a single frequency marker at the center of the
active trace if a marker is 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 appear at the center of
the display. The amplitude and frequency (or
time) of the first marker is fixed. 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.
