In an optical spectrum analyzer, the respective wavelength bandwidths of the optical spectrum analyzer are determined at the wavelengths of the reference lines and used as calibration data for determining measurement tolerances by means of reference lines of known wavelength and known wavelength bandwidths from the known wavelength bandwidths of the reference lines and from the wavelength bandwidths of the reference lines measured with the optical spectrum analyzer
