Check the listed channels to ensure that channels that you know are

not video are not listed as video channels. If during the Build Chan-

nel Plan phase the receiver detects a signal at a video carrier fre-

quency it assumes it is a video channel. Some FM carriers may

happen to fall at video carrier frequencies for channels 95-97. Be sure

these channels are properly designated as video or single carriers. FM

signals may be entered as channels, but must be designated as Single

Carriers.

At this time be sure to edit each scrambled channel to ensure that it

is designated appropriately. A special algorithm is used to ensure that

the peak of these signals is measured.

At this time you may also wish to designate tilt channels, and label

the channels with call letters, but this is not essential to begin the

measurement process.

4.3 SETUP

There are four setup modes for the 3HRV; General, Measurements,

Channel Plan, and Reverse Sweep. General setup allows the operator

to configure general aspects of the unit (not specifically related to

measurements) for personal taste. Measurements setup permits the

operator to setup certain parameters that apply to specific measure-

ments. Channel Plan setup allows the operator to configure channel

tuning to match the specific characteristics of a particular cable

system. Reverse Sweep setup lets the operator setup reverse sweep

receiver parameters.
