Freq:1200.0000 MHz Spectrum:Normal
Rxα:.20 GoldCode:000000 ()
The Spectrum Inversion status is read-only. The active status displays as either Normal or
Inverted.
The active Rxα (Rx Alpha Filter Rolloff Factor) status is read-only. The displayed value depends on

Use the   arrow keys to select a digit, and then use the  arrow keys to change that digit.
Press ENTER.
(CONFIG: Rx) Freq  GoldCode (Gold-n Index Code)
CRITICAL – Make sure that the Rx GoldCode value matches the Tx GoldCode value
of the distant end modem.
The GoldCode indicates the Physical Layer spreading sequence number. Use the   arrow keys
to select a digit, and then use the  arrow keys to change that digit. Press ENTER. Valid
settings are:
