Abstract

Optical wavelength sensitivities in an optical meter used for a sweep synchronization measurement are corrected by a method comprising the steps of measuring a plurality of reference values when no device under test is connected to the optical meter, computing a series of corrective values for the reference values for a plurality of selected reference wavelengths, respectively, such that the reference value at one of the selected reference wavelengths is zero, correcting a plurality of actual measured values using the series of corrective values when an device under test is connected to the optical meter, and displaying the actual measured values corrected.
