the Edit Box below the list. You can change the frequency by using the

numeric keys followed by the Enter key. The list will be updated when

the Enter key is pressed.

4. To remove a sweep point, use the up or down keys to select the

point, then press the Delete soft key.

5. Press the Add soft key to insert a new sweep point into the plan. The

new point will be at the same frequency as the point that was selected

when the Add soft key was pressed. You must set the new point to the

correct frequency using the Edit Box.

soft key to return to the previous screen.

Testing the Transmitter Setup for Reverse Sweep

It is best to test the transmitter setup and connection within the headend

before proceeding into the field. The following tips should help in the

debugging process:

1. Find an available input on the return path combining network. Connect

this point to the OPT port of the SDA-5000 you’re using for reverse

sweep. Leave in place the forward path connection described in

"Testing the Transmitter Setup for Forward Sweep" (page 283).
