r Rate
Status
Command:
Response:
Where:
nnnnn = One of the following decoder rates:
1/2 (QPSK 1/2)
3/4 (QPSK 3/4)
7/8 (QPSK 7/8)
16Q34 (16QAM 3/4)
16Q78 (16QAM 7/8)
8P23 (8PSK 2/3)
8P56 (8PSK 5/6)
N/A (Not Assigned)
mmmmm.mmm = Data rate in kHz.
Receive
Signal Level
Status
Command:
Response:
Where:
x = < or > (data modifier to indicate that the receive
signal level is less than or greater than the returned
value).
s = + or - (receive signal level sign, plus or minus).
nn = 0 to 99 (receive signal level magnitude).
Notes:
1. The 'x' (< or >) parameter is only returned if the
level has exceeded the computational resolution of
the system.
2. 'No Data' is returned if the level cannot be
calculated.
3. 'Sampling' is returned if not enough data is currently
available to calculate the level.
Interface
Buffer Fill
Status
Command:
Response:
Where: nn = 1 to 99 (relative to buffer depth).
Current
Sweep
Value
Command:
Response:
CD_xxx'cr''lf']
Where:
s = + or - (sweep offset from center).
nnnnn = 0 to 60000.
xxx = OK or FLT (decoder lock status OK or FAULT).
This command returns the current sweep value and the
decoder lock status.
