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:
> More > Spectrum Emission Mask > 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:
> More > Spectrum Emission Mask > 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:
> More > Spectrum Emission Mask > 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.
