Abstract
An optical spectrum analyzer includes an optical section 130 for executing light dispersion into a spectrum and wavelength sweep for input measured light, converting the measured light into an electric signal, and outputting the electric signal, a control section 101 for controlling the wavelength sweep of the optical section and outputting a sampling clock of a period shifting from a cycle period of the measured light for each wavelength of the wavelength sweep, and a measurement section 140 for executing sequential sampling of the electric signal from the optical section for each sampling clock.
