the user has performed the internal wavelength calibration using a source of
known wavelength.
Reproducibility
refers to the amount of wavelength drift which can occur
over the specified time while the OSA is swept across a source of known wave-
length.
Tuning Repeatability
refers to the wavelength accuracy of returning to a
wavelength after having tuned to a different wavelength.
Resolution FWHM
