Description
This
softkey
causes the difference in frequency between two markers
to appear on the swept signal generator display. The frequency
difference is indicated in the following format:
-->
DELTA MARKER
Im
-
nl
XXXXX MHz, where
m=
the last marker activated, n= the
reference marker, and XXXXX represents some frequency value.
On a CRT display, the trace between the two selected markers is
intensified. An asterisk next to the key label indicates that this
feature is active.
At preset (factory), the swept signal generator is set to measure the
difference between M2 and Ml
(
marker reference). If markers have
not been activated after preset, selecting Delta Marker indicates
the difference between M2 and Ml. Both of these markers have an
asterisk next to their key label, indicating that they are on.
Whenever Delta Marker is selected, it reactivates the last marker
selected and makes that marker the “m” frequency. If the delta
marker feature is active, selecting a marker causes the “m” frequency
to change to the marker selected. If a frequency entry is made when
delta marker is in the active entry area, the frequency value of the
“m” frequency is changed to the new frequency entry causing the
new difference in frequency to be displayed. Negative frequency
differences are possible if “n” is greater than “m”.
