13. By clicking the "Stats & Spectrum" tab at the top of the utility's window, you
will see a window that allows you to examine the AW2400mSPI's reported status
information and to perform a spectrum scan of the 2.4 GHz frequency band to
look for interference sources:
14. The Stats & Spectrum Serial Port selection should be the same as that on the
previous page. By clicking "Get Stats", the radio's status information will be
read from the AW2400mSPI and displayed. The parameters are self-explana-
tory. Until you exchange data as described below, the packet counts and sizes
may all be zero.
15. On the right side of the window you can cause the AW2400mSPI to do a spec-
trum scan as described in the getRSSIReadings command explanation earlier
in this manual. You can select the frequency step size and number of samples
to be averaged at each frequency, then execute a single scan with the "Get
Spectrum Scan" button, or continuously scan by checking the box. Continuous
scanning will obviously degrade data transmission performance.
16. You should do a spectrum scan with the AP unit. Before it scans, it shuts off
its transmitter and tells any connected SUs to do the same, then steps the re-
ceiver through the band. If you do a scan with an SU, you will likely see peaks
of transmission from the other radios.
