Disconnecting a Spectrum Device
A spectrum monitor or hybrid AP can send spectrum analysis data to only one client at a time. When you are
done viewing data for a spectrum device, you should release your client’s subscription to that spectrum device
and allow other clients to view data from that device. A spectrum monitor or hybrid AP automatically
disconnects from your client when you close the browser window used to connect the spectrum device your
client.
To manually disconnect a spectrum monitor or hybrid AP:
1. Click the Spectrum Monitors tab.
2. Each table entry in the Currently Connected table includes a Disconnect link to release the client’s
connection to that spectrum monitor. Identify the table entry for the spectrum monitor you want to
release then click Disconnect.
3. A pop up window asks you to confirm that you want to disconnect the spectrum monitor from the
spectrum analysis client. Click OK. The spectrum monitor disconnects from the client and the device’s entry
is removed from the Currently Connected table.
When you disconnect a spectrum device from your client, the AP continues to operate as a spectrum monitor
or hybrid AP until you return the device to AP mode by removing the local spectrum override, or by changing
the mode parameter in the AP’s 802.11a or 802.11g radio profile from spectrum-mode to AP-mode.
If you are use Internet Explorer with multiple instances of the Internet Explorer browser open, and you close the
spectrum browser window without manually disconnecting the spectrum device, the controller does not release the
data streaming connection to a spectrum monitor until 60 seconds after you close the spectrum client browser
window. During this 60-second period, the spectrum monitor is still connected to the client.
Configuring the Spectrum Analysis Dashboards
Once you have connected spectrum monitors to your spectrum analysis client, you can begin to monitor
spectrum data in the spectrum analysis dashboards. There are three predefined sets of dashboard views, View
1, View 2 and View 3. View 1 displays the Real-Time FFT, FFT Duty-Cycle and Swept Spectrogram graphs by
default, and Views 2 and 3 display the Swept Spectrogram and Quality Spectrogram charts, and the Channel
Summary and Active Devices tables.
Each chart in the dashboard can be replaced with other chart types, or reconfigured to show data for a
different spectrum monitor. Once you have configured a dashboard view with different settings, you can
rename that dashboard view to better reflect its new content.
The following sections explain how to customize your Spectrum Analysis dashboard to best suit the needs of
your individual network:
