This sequence allows the user to create a channel plan by "learning"
the channels on a cable system.
NOTE: Ensure that the 3HRV is connected to the cable system.
Step 1: Enter a name for the new channel plan that will be built.
Use the alphanumeric keypad to enter a channel plan name. Press
the
OK
soft key when completed.
Step 2: Select a fixed channel plan to use for building the new plan.
Use the

build the new plan from. Press the

soft key when completed.
Step 3: Enter the frequency at which to stop searching for channels.
Press the
ENTER
key followed by the
OK
soft key to set the
stop frequency.
The 3HRV will sequence through all channels in the selected fixed
plan until the stop frequency is reached. This operation can be
terminated by pressing the
Stop
soft key. When completed, indi-
vidual channels contained in the newly built plan can be edited.
NOTE: Some channel plans have interlaced channels. To prevent
interference, delete interlaced channels prior to building
sweep points.
