The total power utility will display the total RMS power level for the entire spectrum and is equal to the total power bar on the right side of the spectrum view. The weighting (Flat, A, B or C) used for this utility is set under the Scaling options dialog box. This is equivalent to the readings on a Sound Level Meter with calibrated to units of SPL.
This utility window can be resized as required by the user and its contents will update anytime a new spectrum is computed. If the analyzer is configured to display the spectrum of both the left and right channels, this utility window will also show the value for both channels. The left channel value will appear above the right channel value.
The contents of any open utility window will be printed on the right margin of the spectrum view.
