Response to
Query
Rx FEC Code
Rate
RCR=
1 byte,
value of 0 thru 7,
A to R
Command or Query.
Sets or returns Rx FEC Code Rate in the form x, where:
0 = Rate 5/16 (Turbo Only)
1 = Rate 21/44 (Turbo Only)
2 = Rate 1/2
3 = Rate 2/3 (8-PSK TCM or 8-QAM only)
4 = Rate 3/4
5 = Rate 7/8
6 = Rate 0.95 (Turbo Only)
7 = Rate 1/1 (Uncoded or No FEC)
8 = Reserved
9 = Reserved
The remaining entries are valid only in CDM-570A Compatible Mode
(CMO=1):
A = VersaFEC CCM – BPSK Rate 0.488
B = VersaFEC CCM – QPSK Rate 0.533
C = VersaFEC CCM – QPSK Rate 0.631
D = VersaFEC CCM – QPSK Rate 0.706
E = VersaFEC CCM – QPSK Rate 0.0803
F = VersaFEC CCM – 8-QAM Rate 0.576
G = VersaFEC CCM – 8-QAM Rate 0.642
H = VersaFEC CCM – 8-QAM Rate 0.711
I = VersaFEC CCM – 8-QAM Rate 0.780
J = VersaFEC CCM – 16-QAM Rate 0.644
K = VersaFEC CCM – 16-QAM Rate 0.731
L = VersaFEC CCM – 16-QAM Rate 0.780
M = VersaFEC CCM – 16-QAM Rate 0.829
N = VersaFEC CCM – 16-QAM Rate 0.853
O = VersaFEC CCM ULL– BPSK Rate 0.493
P = VersaFEC CCM ULL– QPSK Rate 0.493
Q = VersaFEC CCM ULL– QPSK Rate 0.654
R = VersaFEC CCM ULL– QPSK Rate 0.734
Note: Selection availability depends on the active FEC and demodulation
type.
