5. Enter the password (default is “password”) and click “Login”. You will then see

the main spectrum analyzer window similar to this:

6. The spectrum analyzer controls are quite simple:

• The “Scan Now” button initiates a spectrum scan.

• The Automatic Scan Interval dropdown allows you to select the time between

scans. Note that more samples per point and finer frequency resolution will

take longer, up to 2 seconds for a step size of one and 256 samples per point.

• The Samples Per Point dropdown controls how many measurements are taken

at each frequency and averaged together.

• The Frequency Step Size dropdown controls the frequency resolution of the

scan. A step size of one provides 128 samples across the range, about 500 kHz

per step (actually 520.8 kHz).

7. The graph shows both peak and average dBm readings. Optionally, you can dis-

play markers on the graph corresponding to the 12 channels that AvaLAN radios

employ in the 900 MHz band. If you wish to make a hard copy of the graph, you can

use your browser printing capability or any of a number of screen capture methods.
