Initial S/W Revision
Sweep Type
Chooses between the FFT and Sweep types of sweep.
Sweep Type refers to whether or not the instrument is in Swept or FFT analysis. When in Auto, the
selection of sweep type is governed by two different sets of rules, depending on whether you want to
optimize for dynamic range or for speed.
FFT "sweeps" should not be used when making EMI measurements; therefore, when a CISPR detector
(Quasi Peak, EMI Average, RMS Average) is selected for any active trace (one for which Update is on),
the FFT key in the Sweep Type menu is grayed out, and the Auto Rules only choose Swept. If Sweep
Type is manually selected to be FFT, the CISPR detectors are all grayed out.
FFT sweeps will never be auto-selected when Screen Video, Log Video or Linear Video are the selected
Analog Output.

For a backward compatibility, the following remote parameters
AUTO
SWP
will be supported by the [:SENSe]:SWEep:TYPE command.
In Zero Span, this key is irrelevant and cannot be accessed (because the whole
Sweep Setup menu is grayed out in Zero Span), however its settings can be
changed remotely with no error indication.
When Gate is on, Gate Method selection affects Sweep Type:
Method FFT&Sweep menu
FFT - Swept grayed out and rules choose FFT
Video - FFT grayed out and rules choose Swept
LO - FFT grayed out and rules choose Swept

[:SENSe]:SWEep:TYPE AUTO sets sweep type Auto to On
