Offset Select the offset pairs (upper and lower) that the softkeys will affect,
and displays the memory selection menu from
A
to
E
(the analyzer
can store up to 5 sets of values for
Start Freq
,
Stop Freq
,
Sweep Time
,
Res BW
,
Meas BW
,
Abs Start
,
Abs Stop
, etc.). Press
Offset
to select
the letter of the desired offset is underlined. Only one selection at a
time is shown on this key label.
Key access:
Meas > SEM > Offset/Limits
Start Freq
On Off
Specifies the inner limit (frequency closest to the carrier) for both
segments of the specified offset pair. When
Start Freq (Off)
is
selected, the offset pair is not measured.
Key access:
Meas > SEM > Offset/Limits
Stop Freq Specifies the outer limit (frequency furthest from the carrier) for
both segments of the specified offset pair. The minimum frequency
difference between
Start Freq
and
Stop Freq
is limited to 100 Hz.
Key access:
Meas > SEM > Offset/Limits
Sweep Time
Auto Man
Specifies the sweep time for the currently selected offset, and
toggles this function between
Auto
and
Manual
for each offset.
