CORRECTIVE ASSIGNMENT TO CORRECT THE NATURE OF THE CONVEYANCE. Provided is an optical spectrum analyzer capable of stably measuring a spectrum of pulsed light while suppressing a decrease in a sweep speed. An A/D conversion unit 17 has a plurality of inputs to which the outputs of a plurality of amplifiers Amp21 to Amp2m are connected. Optical spectrum analyzers are particularly useful for analyzing light sources for optical telecommunication, where it is preferable to ensure that the optical. (57) An optical spectrum analyzer (20) measures to-be-measured light while carrying out calibration processing for correcting wavelength information of spectrum data of the to-be-measured light by a wavelength information correction device (56) through a storage device (58) based on the spectrum. An optical spectrum analyzer is provided that can separate measurement target light into orthogonal polarization components and perform measurement and enable optical spectrum measurement that does not depend on polarization of the measurement target light.
