Users Guide

The Spectrum Analysis section of the Monitoring tab in the WebUI includes the Spectrum Monitors,
Session Log, and Spectrum Dashboards windows.
l Spectrum Monitors: this window displays a list of active spectrum monitors and hybrid APs streaming
data to your client, the radio band the device is monitoring, and the date and time the SM or hybrid AP was
connected to your client. This window allows you to select the spectrum monitors or hybrid APs for which
you want to view information, and release the connection between your client and any device you no longer
want to view.
l Session Log: this tab displays activity for spectrum monitors and hybrid APs during the current browser
session, including timestamps showing when the devices were connected to and disconnected from the
client, and any changes to a hybrid APs monitored channel.
l Spectrum Dashboards: this window shows different user-customizable data charts for 2.4 Ghz and 5
GHz spectrum monitor or hybrid AP radios. Table 155 below gives a basic description of each of the
spectrum analysis graphs that can appear on the spectrum dashboard.
For more detailed information on these graphs, refer to Customizing Spectrum Analysis Graphs on page 747.
