Source

Multiplier Denominator

The multiplier denominator parameter offsets the source frequency from the analyzer frequency.
The source frequency tracks the SA frequency according to the source frequency equation shown
under the Source, Frequency key description.

The multiplier denominator must be restricted to operate within the range of the source minimum
and maximum frequencies.

Source Sweep Reverse

Allows you to reverse the source sweep direction

Normally, the source will sweep from a lower frequency to a higher frequency. However, there are
test scenarios in which the source sweep needs to be “reversed”. In this case, it sweeps from a
higher frequency to a lower frequency. For example, when the DUT is a frequency converter and a
measurement of the Lower Side Band characteristics is desired, a reverse sweep is employed.
Reverse sweeps are supported for such scenarios, but two cautions are in order:

1. Reverse Sweep only reverses the direction of the source’s sweep, not the analyzer’s sweep.

Unless you are actually using a device like a frequency converter and looking at the lower
sideband, thus effectively reversing the direction of the source’s sweep, the source will be
