Reading the Spectrum Analyzer

The Spectrum Analyzer actively scans the 5 GHz band in the background to report on interference sources that may

impact link performance by frequency, amplitude, and probability of recurrence. The display can be shown for the

local radio, remote radio or a combination of both. Click on the half circle icon in the upper right to toggle the

graph's background color between black and white. Click the Local, Remote, or Combined buttons to view spectrum

individually or simultaneously. Please note that the remote side data may be as much as 5 minutes behind the local

radio.

Channels that are already in use have “above average” amplitude on the vertical axis, and are shaded in different

colors to represent how often the signals are likely to be on the same frequency at the same amplitude. The legend

to the right of the graph explains the color code for the Cumulative Distribution Function (CDF). The color red

suggests the highest probability (closer to 1), while blue represents the lowest probability (closer to 0).

There are three types of markings, or bars, immediately beneath the graph’s horizontal axis that indicate frequency

ranges that are restricted, manually excluded, or in active use by this link. Note that traffic from the Active Channel

is excluded from the display so that noise can be detected.
