available on instruments with firmware revisions ≤920528, or with
Option 008. The frequency-shift method of identifying valid signals
uses the spectrum-analyzer function

Any signal not produced by the currently selected harmonic will be
shifted horizontally on alternate sweeps (see Figure 2-48).
Therefore, when viewing the display, on alternate sweeps the signal
will appear, then not appear, at the frequency of interest. The correct
signal produced by the selected harmonic will be shifted in a vertical
direction only, as in Figure 2-49.
