Maximum

Maximum is the maximum amplitude of the waveform's displayed power or voltage.

The maximum level is taken directly from the histogram data. The measurement can be restricted to a region. A level annotation label is placed at the maximum result. The entire screen is the interval over which the measurement is made.

The measurement can be performed on any waveform that is displayed in one of a Waveform content windows.
