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
DIAG.
port to enter an
update mode, and the signal-to-noise ratio is updated and redisplayed
every 2 seconds. The SNR continuously updates until the key is
pressed.
SPECTRUM [xxx.xx]
Internal Spectrum
Analyzer
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 spectrum at the command prompt. A
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 spectrum xxx.xx,
where xxx.xx 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.
