Command or Query.
Sets or returns Tx 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

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 Modulation type.
Example: <0/TCR=4 (Rate 3/4)
Command or Query.
Sets or returns Tx Data rate in the form xxxxx.xxx, where:
xxxxx.xxx = value from 2.4 kbps to 10240 kbps
Resolution = 1 bps.
Examples:
1) <0/TDR=02047.999 (2047.999 kbps in CDM-570A Compatible Mode)
2) <0/TDR=2047.999 (2047.999 kbps in CDM-570 Compatible Mode)
