Spectrum Analysis
Spectrum analysis provides two real time views of the RF environment using data
generated by the AP to chart power levels across the 2.4 and 5GHz frequency
bands.
• Instantaneous Samples View (top view): The instantaneous samples plot
provides a real time display of signal power across the entire 2.4 or 5GHz
frequency bands. The plot is color-coded based on the signal power within each
part of the frequency band. Red represents stronger signals while weaker signals
are closer to blue.
• CDF of Samples View (bottom view): This graph displays the concentration of
signal power readings within each portion of the frequency band in a cumulative
distribution format. The CDF plot is color-coded based upon the frequency with
which each point is observed during consecutive spectral sweeps of the entire
2.4/5Ghz frequency band. Frequently occurring points are marked ‘red’, moder-
ately occurring points are marked ‘yellow’, and occasionally occurring points are
marked ‘green’.
To view spectrum analysis data for an access point:
1 Go to Monitor > Access Points and click the MAC address of the AP to view
the AP detailed information page.
2 Click the Spectrum Analysis icon in the “Actions” table. (APs that do not support
this feature do not display this icon).
3 The Spectrum Analysis display opens in a new window.
4 Select 2.4G or 5G to choose the frequency band for which spectrum analysis
data will be collected and click Start Monitoring to begin.
