The SNR is an indication of the received signal quality. A value of
10 dB represents a very poor signal. A value of 24 dB represents a very
good signal.
When the SNR command is used, it causes the
update mode, and the signal-to-noise ratio is updated and redisplayed
every 2 seconds. The SNR continuously updates until the
pressed.

SPECTRUM [xxx.xx]

Activates the built-in spectrum analyzer tool (see Figure 18) that can be shown
on a connected PC. This tool is helpful in diagnosing interference problems on
or near your channel frequency.
Access the spectrum analyzer by entering
display appears showing detected signals on your current channel.
Optionally, you can specify a frequency at the command prompt to view the
surrounding spectrum of that frequency. To do this, enter
where is the frequency in MHz.

A typical spectrum analyzer display is shown in Figure 18. The display creates
a received signal strength indication (RSSI) vs. frequency plot for the fre-
quency and surrounding signals. By analyzing the display, you can determine
the presence of other signals near the transceiver's operating frequency. This
information can be helpful in troubleshooting interference problems.
