Spectrum Trace View

Parent Previous Next


Clear Waves continuously scans and samples the signal strength (dBm) of frequencies in the range the user has specified. In the Spectrum Trace view the signal strength data (in dBm) is displayed as a function of frequency. 

By default 2 traces are displayed -- Current (green) and Maxima (red). The Current trace displays the signal strength data from the most recent scan. The Maxima trace displays the maximum signal strength for each frequency since the scan session began.  Optionally, a Reference (blue) trace may also be displayed -- see Menu Options > Reference Trace.


 

In the upper-right-hand corner of the Spectrum Trace view there is a small rectangle that displays the current [x,y] grid coordinates in MHz and dBm. As you move the mouse cursor around the chart, these coordinates are continuously updated.


 

 

 

When you right-click the mouse button, a popup menu appears with several choices you can select from:


These choices are discussed further below:

 

Full Screen view

 

When you select Full Screen from the popup menu, the Spectrum Trace view will enlarge to fill the entire screen, and the two lower windows will become minimized. To restore the Spectrum Trace view to its original dimensions, access the popup menu by right-clicking the mouse and select Restore Screen.

 

 

 

Left Button used for creating Marker points or 'Hot Spots'

 

When you select Left Button: Marker Points from the popup menu then subsequent left-clicks create Markers or "Hot Spots" that display the corresponding frequency (in MHz) and signal strength (in dBm) for the location in the grid that you just clicked on.


Clear Markers from the display

 

If the Spectrum Trace view becomes too cluttered with Markers, they can be quickly removed by selecting Clear Markers from the popup menu.

 

   

Hide Maxima Trace

 

When you select this option from the popup menu, the Maxima trace will no longer be displayed. If the Maxima trace is currently hidden and you want it to be displayed again, then select Show Maxima Trace from the popup menu.



Hide Reference Trace

 

When you select this option from the popup menu, the Reference trace will no longer be displayed. If the Reference trace is currently hidden and you want it to be displayed again, then select Show Reference Trace from the popup menu.  In order to show a Reference trace it is first necessary to save a trace to a file -- see section Menu Options > Reference Trace.
