RC (Ambient Power - Single Channel) Command
<Diagnostics> The RC command is used to examine and report the power level on a given channel.
Sample output:
-78 dBm [when CF = 0]
4e
[when CF = 1]
-78 [when CF = 2]
RE (Restore Defaults) Command
<Diagnostics> The RE command is used to restore all configurable parameters to their factory default settings.
The RE Command does not cause default values to be stored to non-volatile (persistent) memory. For the restored
default settings to persist in the modem’s non-volatile memory and be saved in the event of RF modem reset or
power-down, the WR (Write) command must be issued prior to power-down or reset.
RM (Ambient Power - All Channels) Command
<Diagnostics> The RM command is used to examine and report power levels on all channels. If no parameter is given,
the channels are scanned one time. If a parameter is given, the channels are repeatedly scanned for that number of
seconds. The maximum power level seen for each channel is reported (i.e. peak hold).
A graphical spectrum analyzer can be implemented by repeatedly sending the RM command (with no arguments) and
reading the resultant 50 power levels (this is easiest to do when CF = 1 or 2).
Sample output [when CF = 0]:
Ch 0: -100 dBm
Ch 1: -103 dBm
...
Ch 49: -99 dBm
Sample output [when CF = 1]:
64
67
...
63
Sample output [when CF = 2]:
100
-103
…
-99
