Rev. 6 B–63
B.2.8.9 E
b
/N
0
The E
b
/N
0
status command causes the E
b
/N
0
ratio to be returned. E
b
/N
0
is returned in dB.
Command:
Response: >add/EBN0_n.ndB”cr””lf”]
Example: Request E
b
/N
0
ratio from modem 2.
Command: <2/EBN0_”cr”
Response: >2/EBN0_6.2dB”cr””lf”]
Where: E
b
/N
0
= 6.2 dB.
Notes:
1. E
b
/N
0
limits are lower < 3.2 dB, upper > 9.7 dB.
2. “No Data” is returned if no carrier is detected (decoder not locked).
B.2.8.10 Modulator Rate
Command:
Response: >add/MR_nnn_mmmm.m”cr””lf”]
Where:
nnn = 1/2, 3/4, 7/8, or BP12 (Coder rate).
mmmm.m = 9.6 to 4080.0 (Data rate).
Note: The parameters “nnn_mmmm.m” may be replaced by “N/A” to indicate “no
assignment.”
B.2.8.11 Demodulator Rate
Command:
Response: >add/DR_nnn_mmmm.m”cr””lf”]
Where:
nnn = 1/2, 3/4, 7/8, or BP12 (Decoder rate).
mmmm.m = 9.6 to 4080.0 (Data rate).
Note: The parameters “nnn_mmmm.m” may be replaced by “N/A” to indicate “no
assignment.”
