Allows adjusting the I/Q offset in OQPSK mode for test purposes
Enter any value from +0.5 to -0.5 (in symbol). Select 0 for optimal OQPSK (half-
symbol offset).
This parameter is not yet available
Convolutional encoder setting for the I and/or Q Channel

OFF: disabled

G1 – G2 Inv: G2 inverted (G1 first)

G1 – G2: G2 normal (G1 first)

G2 Inv – G1: G2 inverted (G2 first)

G2 – G1: G2 normal (G2 first)
Refer to the CCSDS recommendations for "G2 normal/inverted" definition

Single – 1 I+Q: Single encoder common to I & Q Channels

Dual – 1I / 1Q: Separate encoders for I & Q Channels
