Scan Rate

Two scan rates are available in the Scan mode, normal and fast. The

scan rate is selected in the Measurement Setup menu. The Fast scan

feature allows for rapid scan displays, while sacrificing accuracy.

Normal scan rate is slower, but much more accurate. An indicator

appears in the upper left hand corner of the Scan screen when the

Fast Scan mode is selected.

Audio Carriers

If desired, the audio carriers can be omitted resulting in a faster scan.

This feature is selected in the Measurement Setup menu. An

indicator appears in the upper left hand corner of the Scan screen

when audio carriers are omitted.

Limits

The Limits feature allows for comparison of the current scan mea-

surement with the "FCC" limits that are defined in Setup. There are

two parts to this feature.

When an out of tolerance condition exists a set of annunciators will

appear below the scan graph. The annunciators indicate the following

out of tolerance conditions:

• Adjacent Channel Error

• Video Level Too High/Low

• ∆VA Too High/Low

The limit annunciators are updated with each scan update.
