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 module’s
non-volatile memory and be saved in the event of RF module 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
