4 Key Reference
Off Turns off the selected marker by the Select Marker key. Off
also turns off the related functions such as signal track. It
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
frequency/time and amplitude differences
between the two markers. 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
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 above the marker (for example, 1R) and the
delta marker is indicated with a marker number.
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 a marker number. Adjusting the
span changes the frequency difference between
the two markers while maintaining the midpoint
between the two markers at a fixed frequency.
Changing the 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, but not
their frequency values when you change a parameter that redefines
the x-axis scale. Reset these markers when parameters such as Span
or Center Freq are changed.
