Chapter 4, Description of Fields
Fields
Normalize
This field is displayed when the Controls field is set to Auxiliary. 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-B displays the difference between the trace saved using Save B and the currently-
displayed trace. The comparison can yield either losses or gains in amplitude.
GPIB Example
“DISP CSP;CSP:TRACE:NORM ‘A only’”
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 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 or A-B functions.
