Control Fields for Analog Measurements

Normalize

This area performs three display operations:

Save B saves the currently displayed trace for the A-B operation.

A Only provides a continuously updated display (the “normal” mode of operation).

A-Bdisplays the difference between the trace saved using Save B and the currently displayed trace. The comparison can yield either losses or gains in amplitude.

Operating Considerations

The A-B function works correctly only if the center frequency and span settings are the same for both signals.

The reference level (Ref Level) can be changed (on the Main controls menu) to move the trace below the top line of the display if the A-B function results in a gain.

The Hold key can be used to “freeze” the display at any time. This allows you to view a trace before performing the Save B or A-B functions.
