Spectrum Data Graphs

When Wi-Spy is plugged in, a live spectrum picture is displayed on the central pane of the main TamoGraph window, as shown below.

spectrum

The spectrum pane is similar to the one you can see in Chanalyzer, a spectrum analysis application by MetaGeek that comes with Wi-Spy. By default, the spectrum pane displays one or two planar spectrum graphs for single- and dual-band Wi-Spy models, respectively.

The appearance of the graphs can be controlled via the context menu. Select 2.4 GHz, 5.0 GHz, or Dual to have the spectrum pane display one of the single frequency bands or two bands simultaneously (5.0 GHz and Dual are available only if you have a dual-band Wi-Spy model.) Select Current Level to display a line that shows the current signal amplitude; select Max Level to display a line that shows the maximum signal amplitude. The X-axis item allows you to select the measurement units of the horizontal axis; you can choose between Frequency in MHz and Channel numbers. By enabling the Waterfall view, you can have the application graph amplitude over time. Select 1/3, 1/2, or 2/3 of the window size to adjust the area of the window occupied by the waterfall graph. The spectrum pane can be detached from the main application window and displayed as a separate floating window. Use the Detach Window and Attach Window to perform the respective operations. You can also hide the spectrum pane by checking or unchecking the View => Spectrum item in the main application menu.

Note that in order to view spectrum data in TamoGraph, you must close Chanalyzer if it is running; Wi-Spy cannot be accessed and controlled by multiple applications simultaneously.
