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.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.
