The present invention relates to a distortion analyzer that is comprised of a converter for converting a signal outputted by optical apparatus into an electrical signal and splitting the converted signal into a plurality of signals. The analyzer also includes first, second, and third analyzer sections for receiving respective ones of the plurality of signals such that the first analyzer section operates to pass the entire spectrum of the outputted signal, the second section operates to pass only that portion of the entire spectrum that is below a predetermined frequency and the third section operates to pass a predetermined band of the entire spectrum. A summing unit is provided for summing the outputs of the first and second sections and subtracting the output of the third section from the summed result to generate a distortion indicator and supplying the distortion indicator to the optical apparatus.
