Read Error
Status
Command:
Response:
Where:
tttt = FRM (FRAME) or 2047 (indicates type of error
being read).
x = < or > (data modifier to indicate that the error rate is
less than or greater than the returned value).
m.m = 1.0 to 9.9 (error rate mantissa).
ee = 1 to 99 (error rate exponent).
This command returns frame or 2047 error rate. The 'IRE_'
configuration command is used to select reading of frame or
2047 errors.
Notes:
1. The 'x' (< or >) parameter is only returned if the error
rate has exceeded the computational resolution of
the system.
2. 'No Data' is returned if the error rate cannot be
calculated.
3. 'Sampling' is returned if not enough data is currently
available to calculate the error rate.
Eb/N0 Status
Command:
Response:
Where:
x = < or > (data modifier to indicate that the Eb/N0 is less
than or greater than the returned value).
nn.n = 1.0 to 99.9 (Eb/N0 value).
Notes:
1. The 'x' (< or >) parameter is only returned if the
Eb/N0 has exceeded the computational resolution of
the system.
2. 'No Data' is returned if the Eb/N0 cannot be
calculated.
3. 'Sampling' is returned if not enough data is currently
available to calculate the Eb/N0.
Modulator
Rate Status
Command:
Response:
Where:
nnnn = 1/2 (QPSK 1/2), [Coder rate], 3/4 (QPSK 3/4), 7/8
(QPSK 7/8), BP12 (BPSK 1/2), QPSK (QPSK 1/1).
mmmm.mmm = Data rate in kHz.
Demodulator
Rate Status
Command:
Response:
Where:
nnnn = 1/2 (QPSK 1/2), [Decoder rate]. 3/4 (QPSK 3/4),
7/8 (QPSK 7/8), BP12 (BPSK 1/2).
mmmm.mmm = Data rate in kHz.
