Source
Amptd Step Auto/Man
Allows you to set the step size associated with the Source > Amplitude key. When auto-coupled, the
step size is the current Scale/Div setting under the Amplitude hardkey (note that this is true even if
the analyzer is currently in Linear amplitude scale).
Once a step size has been selected and the Source Amplitude function is active, the step keys
(and the UP|DOWN parameters for Source Amplitude from remote commands) change the Source
Amplitude by the step-size value.
You may change the step size manually by pressing Amptd Step and entering a value. The function
(and the step size) will return to Auto when a Mode Preset or Auto Couple is performed.

Frequency
Allows a you to access the Frequency submenu. This menu lets you use a stepped tracking source
for stimulus/response measurements for some added flexibility. With such a source, the source
frequency does not need to track 1:1 with the analyzer LO frequency, it is possible to measure
scalar harmonic and subharmonic responses of devices. For example, the second harmonic
response is measured by stepping the analyzer and source so that the analyzer is always at twice
the source frequency. In addition, the frequency offset capability allows the measurement of
frequency conversion devices (like mixers).
In tracking mode, the source frequency tracks the analyzer frequency according to the source
frequency equation:
