16QAM – 16 Quadrature Amplitude Modulation.
Rate
•
Viterbi – 1/2; 2/3; 3/4; 5/6; 7/8
•
Uncoded – 1/1
•
Turbo – 5/16; 3/4; 7/8; 17/18; 21/44
•
Sequential – 1/2; 3/4; 7/8
•
ULL – 1/2; 2/3; 3/4

LL – .378; .451; .541; 1/2; 2/3; 3/4; 7/8
•
HP – 1/2; 2/3; 3/4
RS
Reed-Solomon Encoder: On or Off
Diff
Differential Encoder: On or Off
Scram
Scrambling (for energy dispersal):
•
V.35 – ITU standard.
•
MOD-V.35 (Modified V.35) – Comtech EF Data Closed Network with Reed- Solomon
compatible .
•
IBS – Used for IESS-309 operation.
•
Turbo – Synchronous scrambler synchronized to the Turbo block.
•
OM73 – Linkabit OM-73 modem compatibility mode.
•
Synch – Synchronous scrambler synchronized to the Reed-Solomon.
•
Off – Scrambling is disabled.
When changing modulation type, the data rate must be set to a rate supported by the modulation
type or the change to the modulation type will not be allowed. Some choices will only be visible if
the modem is set to a compatible mode, or if an option is installed or enabled.
