Configuring 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 2andView 3. View 1 displays the Real-TimeFFTFast Fourier Transform. FFT is a frequency analysis mechanism that aims at faster conversion of a discrete signal in time domain into a discrete frequency domain representation. See also DFT.,FFTFast Fourier Transform. FFT is a frequency analysis mechanism that aims at faster conversion of a discrete signal in time domain into a discrete frequency domain representation. See also DFT.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.

Spectrum Analysis dashboards are available only on stand-alonecontrollers.

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:

Selecting Spectrum Monitor

When you first log in to theSpectrum Analysisdashboard from theManaged DeviceWebUI,它显示空白的图表。你必须identify the spectrum monitor whose information you want to view before the graphs display any data.

To identify the spectrum monitor radio whose data you want to display in theSpectrum Analysisdashboard, log in to themanaged deviceobtained from theManaged Network节点层次结构(如描述inObtainingManaged DeviceNode Detailssection ofSpectrum Analysis Tasks):

1.In theManaged Devicenode hierarchy, navigate toDiagnostics>Tools>Spectrum Analysis.

2.ClickLaunchto launch the Spectrum Analysis tool.

3.Click theSpectrum Monitorstab in the new window.

4.ClickAdd.

5.Select a spectrum monitor from the list and clickConnect.

After you have selected the initial spectrum monitor or hybrid AP for a graph, you can display data for a different spectrum device at any time by clicking the down arrow by the device name in the chart titlebar and selecting a different connected spectrum monitor or hybrid AP.

Changing Graphs within Spectrum View

To replace an existing graph with any other type of graph or chart, log in to themanaged deviceobtained from theManaged Network节点层次结构(如描述inObtainingManaged DeviceNode Detailssection ofSpectrum Analysis Tasks):

1.In theManaged Devicenode hierarchy, navigate toDiagnostics>Tools>Spectrum Analysis.

2.ClickLaunchto launch the Spectrum Analysis tool.

3.Click theSpectrum Dashboardstab.

4.FromSpectrum Dashboardswindow, click one of the view names at the top of the window to select the dashboard layout with the graph you want to change.

5.Click the down arrow at the far right end of the graph title bar to display a drop-down list of chart options.

6.ClickReplace Withto display a list of available graphs.

7.Click the name of the new graph you want to display.

Renaming Spectrum Analysis Dashboard View

You can rename any of the three spectrum analysis dashboard views at any time. However, renaming a view does not save its settings. (For details on saving a spectrum dashboard view, refer toSaving Dashboard View.)

To rename a Spectrum Analysis Dashboard view, log in to themanaged deviceobtained from theManaged Network节点层次结构(如描述inObtainingManaged DeviceNode Detailssection ofSpectrum Analysis Tasks):

1.In theManaged Devicenode hierarchy, navigate toDiagnostics>Tools>Spectrum Analysis.

2.ClickLaunchto launch the Spectrum Analysis tool.

3.Click theSpectrum Dashboardstab.

4.Click the down arrow to the right of the dashboard view you want to rename.

5.SelectRename.

6.TheDashboard Namepopup window appears. Enter a new name for the dashboard view, then clickOK.

Saving Dashboard View

You can select different graphs to display in a dashboard view, but these changes are not saved unless you save that view. Dashboard views, (like the spectrum analysis profile and spectrum local-override profile) are all local configurations that must be configured on each stand-alonecontroller.

The following procedures save a dashboard view:

1.After selecting the graphs you want to appear in the view, clickSave Spectrum Viewsat the top of the window.

2.TheSpectrum View saved successfullyconfirmation window appears when the spectrum view has been saved.

If you change graphs in a spectrum view but do not save your settings, you are prompted to save or cancel your changes when you close the spectrum dashboard browser window

Resizing an Individual Graph

The left side of the title bar for each graph includes a resizing button on that allows you to expand a graph for easier viewing. Click this button to expand the selected graph to the size of the full window and display theOptionspane, which allows you to change the current display options for that graph. (Configuration options are described inSpectrum Analysis Graph Configuration Options). To close the options pane if you have not made any changes to the graph, clickClose底部的Optionspaneorclick the resize button again to return the graph to its original size. To save any changes to the graph, clickOKto save your settings and close theOptionspane.
