Data Polarity

0 = DVB, 1=DVB-S2, 2=DTV-AMC


in 1 Hz steps, If range = 50 MHz to 180 MHz, L-Band Range =
950 MHz to 2150 MHz


0 = QPSK, 2 = 8PSK, 3 = 16QAM, 4 = 16APSK

1 = 1/2 Rate, 2 = 2/3 Rate, 3 = 3/4 Rate, 4 = 5/6 Rate, 5 = 7/8
Rate, 8 = 8/9 Rate, 9 = 9/10 Rate, 10 = 10/11 Rate, 11 = 11/12
Rate, 12 = 3/5 Rate, 13 = 4/5 Rate, 14 = 6/7 Rate, 15
=Reserved 16 = Reserved, 17 = Reserved

in 1 bps steps

symbols per second

0 = Inverted, 1 = Normal


0 = 0.35, 20 = 0.20, 25 = 0.25

0 = Symbol Rate, 1 = Data Rate , 2 = Auto


in 1 Hz steps, Max 7.5 MHz, Min: Symbol Rate/10 and when
demodulation is 8PSK Min: Symbol Rate/20


0 = disable, 1 = enable


0 = RS422 Serial, 2 = ASI, 3 = AASI, 4=G703E3 UNBAL,
5=G703T3 UNBAL, 6=G703STS1 UNBAL, 7= HSSI, 8 = DVB
Parallel, 9 = M2P Parallel, 10 = ECL BAL/UNBAL, 11 = GIGE

0 = 188 byte, 1 = 204 byte, 2 = no framing

0 = normal, 1 = inverted
