Sweep File Overlay

Sweep file overlay allows a stored sweep response to be viewed

simultaneously with the "live" sweep response for direct comparison.

The Sweep File Overlay option must be enabled to view both traces

simultaneously. With this option disabled, stored files will be dis-

played for normal viewing without the live response superimposed. If

the Sweep File Overlay option is enabled, the live response will

overlay the stored response when viewing the sweep file. Use the UP

and DOWN arrow keys to enable the option.

Include Audio Carriers (Sweepless Mode Only)

This selection allows the audio carriers to be excluded resulting in a

faster sweep. Use the UP and DOWN arrow keys to include (Yes) or

exclude (No) audio carriers.

4.4 HOW TO PERFORM LEVEL MEASUREMENTS

Signal levels are measured in the Level and Scan Modes. The Level

mode display provides both a numeric indication of signal level and

an analog meter. The audio and video carrier levels of a channel are

displayed simultaneously. Alternately, an individual carrier can be

measured (as in the case for a data or pilot carrier) or the unit can be

tuned to a specific frequency.
