7.11.5 Spectrum Analyzer
Spectrum Analyzer helps to analyze a spectrum for interference, and select a relatively low interference channel. This tool is
not a replacement for the commercial Spectrum Analyzers as this is only intended to help with channel selection and
diagnose performance issues.

: Only an administrator user can use Spectrum Analyzer to scan the spectrum. However, the Monitor user can view the
last scanned results.
To scan all the channels in the configured frequency domain, do the following:
•
Navigate to MONITOR > Tools > Spectrum Analyzer. The following Spectrum Analyzer screen appears:

Channel Scan Time: Enter the time (ranging from 100 to 60000 milliseconds) to scan each channel. By default, the
scan time is set to 1000 milliseconds.

The total duration of scan depends on the number of channels available, channel scan time and scan iterations.
•
While scanning, Spectrum Analyzer does not consider channel offset.
•
Spectrum Analyzer detects only 802.11 modulated signals.
•
A minor variation in Spectrum Analyzer results can be expected due to the following reasons: variation in the radio
properties between various device models and Satellite Density Configuration.
