(CONFIG: Tx) Mode

Transmission Mode:
S2-G/S2-TS S DSNG
The TX Mode is a key parameter for setting all modem parameters, and it is generally easier if it
is set first. The Mode determines which modulation, code rates, FEC type and symbol rate range
are available and also if Pilots or Gold Code settings are available. Changing the Mode will
change one or more of these.
Select S2-G/S2-TS, S, or DSNG using the
modes, check the modulation, code, and data rate selections.
