"On"
In this mode, the power level is swept continuously and linearly from
"Start Power" to "Stop Power" (swept mode, faster). For each sweep
point, measurement takes place over a range of power levels.
Assuming the phase drifts linearly during the sweep time, the phase
can be removed from the measurement results.
"Pulsed"
In this mode, for each sweep point the analzer perfoms an additional
measurement at the "Start Power", i.e. the power is rapidly switched
between the stimulus power and the "Start Power". By comparing the
different "Start Power" measurements, the (uncompressed) phase at
each sweep point can be estimated and removed from the measure-
ment.
While this method does not make an assumption on the phase drift, it
assumes that the DUT can cope with rapid power level changes.

Define Segments dialog
The "Define Segments" dialog defines all channel settings for a
frequency
sweep and imports or exports segmented sweep settings.
Access:
Channel – [Sweep] > "Sweep Type" > "Define Segments..."
The dialog contains a table to edit the individual segments of the sweep range. Use the
to select the columns to be displayed and edited.
●
Sweep segments are allowed to overlap.
●
In contrast to standard frequency sweeps, the start and stop frequency in a sweep
segment do not have to be different.
So with a segmented sweep you can measure n
1
points at frequency f
1
(in segment
1), n
2
points at frequency f
2
(in segment 2) etc.
