segments of the specified offset pair. When Start Freq (Off) is
selected, the offset pair is not measured.
Key access: Meas > SEM > Offset/Limits
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
Specifies the sweep time for the currently selected offset, and
