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.
Claims6
A method of correcting optical wavelength sensitivities in an optical meter used for a sweep synchronization measurement, the 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 only the series of corrective values when a device under test is connected to the optical meter;
- and
- displaying the actual measured values corrected.
An apparatus for a sweep synchronization measurement, the apparatus comprising:
- an optical meter for measuring a plurality of reference values when no device under test is connected to the optical meter;
- a controller for 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, the controller for correcting a plurality of actual measured values using only the series of corrective values when a device under test is connected to the optical meter;
- and
- a display for displaying the actual measured values corrected.
