The peak frequency utility will display the frequency of the strongest spectral component in the entire span (not just what is displayed). 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.
If Peak Hold is enabled the utility window will have separate columns for Live and Peak Hold - the text color will match their respective trace colors on the plot.
The contents of any open utility window will be printed on the right margin of the spectrum view.
