CHANNEL PLAN CONFIGURATION

What is a Channel Plan?

A channel plan is a framework of cable network parameters chosen

by the user for his network. The basic entities are:

· Channel format (analog, digital, scrambled, etc.)

· System Bandwidth

· Test Limits (digital and analog)

· Carriers (audio and video)

Why do we need a Channel Plan?

A well thought-out channel plan is necessary for the proper

operation of the unit. This is accomplished by specifying tilt and

scan, and taking full advantage of the Auto Test and Installation

Check features in the Acterna instruments. Remember that the

Acterna instruments are capable of learning a channel plan from a

cable system and storing it as a built-in plan.
