Distortion analyzers produce a low-distortion sine wave signal that is applied as the input signal to the amplifier under test. In turn, the amplifier's output signal is applied back to the distortion analyzer, where the fundamental frequencies of the input signal is subtracted, leaving only the distortion residuals. The ratio of the distortion residuals to the output signal becomes the traditional THD+N specification. Distortion residuals can be observed with an oscilloscope, providing an educated guess of the distortion mechanism creating the distortion.
