Key Reference 4
N9320A Spectrum Analyzer 97
Off Turns off the selected marker by the Select Marker key. Off
also turns off the related functions such as signal track. It
will also removes marker annotation from the display.
Key access:
Use the data control keys to position the delta
marker. Annotation in the active function block
and in the upper- right corner indicates the
differences between the two markers,
frequency/time and amplitude. Delta (Off) moves the
reference marker to the active marker position,
allowing you to make delta measurement from
differing reference points without having to turn
off the markers and begin again.
Key access:

Delta Pair
Ref Delta
Toggles the Delta Pair between the reference (start)
and delta (stop) markers. The start marker number
is indicated with a number and an R (reference)
above the marker (for example, 1R). The delta
marker is identified with the marker number only.
Key access:
> Delta
Span Pair
Span Center
Toggles the Span Pair function between the span
and center markers. The start marker number is
indicated with a number and an R above the
marker (such as 1R) and the stop marker is
indicated with only the marker number. Adjusting
the span changes the frequency difference between
the two markers while maintaining the midpoint at
a fixed frequency. Selecting Center changes the
center point between the two markers while
maintaining the frequency difference.

NOTE
Ref and Delta markers maintain their displayed x-axis location,
however, their frequency values will change if the frequency or span
parameters that define the x-axis scale are changed. Reset these
markers, if necessary, when parameters such as Span or Center Freq
are changed.
