4.2.2 How to Setup for Measurement Modes

The following procedure describes the steps to prepare the 3HRV for

measurement modes.

Building A Channel Plan

1. To build a channel plan, first enter the setup mode by pressing the

SETUP key.

2. Press the Channel Plan soft key, and cursor down the menu to

Build Channel Plan.

3. Press the ENTER key, and you will be prompted at the first step to

name the channel plan to be built. The name should be a logical

one that will be easy to remember. The location of the headend is

usually a good name for the channel plan. When the name is typed

in, press the ENTER key.

4. The next step is to choose a channel plan from the built-in list that

most closely resembles the plan of your system. Typically your

system channel plan will be a subset of the built-in plan. Cursor

down to the appropriate channel plan and press the ENTER key or

the OK soft key.

5. You will then be prompted to enter the highest frequency that you

would like to scan. Type in the frequency and press the ENTER

key followed by the OK soft key. The unit will then commence a

scan for the presence of channels. After the scan is done, this

phase of the channel plan building process is complete. Press the

Exit soft key to return to the Channel Plan menu.

Editing A Channel Plan

The next step is to edit the channel plan to characterize it for your

particular system. Cursor down to Edit Channel Parameters and press

ENTER. A listing of all the channels within the frequency range

designated in the Build Channel Plan phase will appear on the

screen. Notice that there are columns for enabled, channel type,

channel number, label, frequency (video carrier), sweep, tilt, and,

scrambled.

Each of these features for each channel may be edited by cursoring to

the channel to be edited and pressing the Edit soft key.
