Config: Rx) Freq (Frequency) - Comtech EF Data CDM-760 Installation And Operation Manual

Front Panel Operation
CDM-760 Advanced High-Speed Trunking Modem
(CONFIG: Rx) Data  Rx Symbol Rate
Rx Sym Rate = 060140.976 ksps
Set the Rx Symbol Rate to match the Tx Symbol Rate of the distant end modulator. Use the  
arrow keys to select a digit, and then use the  arrow keys to change that digit. Press ENTER.
After the receive path is locked, the Rx menus show the applicable data rate, modulation type,
code rate, pilots ON/OFF, FEC frame length spectral inversion, etc.

6.2.2.3.3 (CONFIG: Rx) Freq (Frequency)

Freq:1200.0000 MHz
Rxα:.20
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
the active network specification:
Network Specification
DVB-S2
DVB-S2-EB1
DVB-S2X
Demodulator Unlocked
Otherwise, use the   arrow keys to select a parameter. Press ENTER.
(CONFIG: Rx) Freq  Freq
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:
Minimum
000000
Spectrum:Normal
GoldCode:000000
