Eb/N0
Status Command:
Response: <add/EBN0_'cr'
>add/EBN0_xnn.ndB'cr''lf'] 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.

nnnn = 1/2 (QPSK 1/2), [coder rate], 3/4 (QPSK 3/4), 7/8

nnnn = 1/2 (QPSK 1/2), [coder rate], 3/4 (QPSK 3/4), 7/8

Receive
Signal Level
Status Command:
Response: <add/RSL_'cr'
>add/RSL_xsnn.ndBm'cr''lf'] 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.n = 0.0 to 99.9 (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

Status Command:
Response: <add/IBFS_'cr'
>add/IBFS_nn%'cr''lf'] Where: nn = 1 to 99 (relative to buffer depth).
