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 AW900mSPI and displayed. The parameters are self-explanatory.
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 AW900mSPI to do a spectrum
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.
17. The peak and average received power at each frequency is displayed in loga-
rithmic graphical form.
