Abstract
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 unithas a plurality of inputs to which the outputs of a plurality of amplifiers Ampto Ampare connected. A control unitselects one of the plurality of amplifiers Ampto Ampwhose output is not saturated based on optical power signals amplified by the plurality of amplifiers Ampto Amp. The control unitsets an average value of the optical power signals sampled by the A/D conversion unitand amplified by the selected one of the amplifiers Ampto Ampas the optical power signal of the next wavelength, while sweeping from the previous wavelength to the next wavelength is performed.
