Definition of Terms
The distinction between specifications and characteristics is described as fol-
lows:
Specifications describe warranted performance.
Characteristics provide useful, but nonwarranted information about the func-
tions and performance of the instrument. Characteristics are printed in
italics.
Absolute Accuracy (after user cal) refers to the wavelength accuracy after
the user has performed the internal wavelength calibration using a source of
known wavelength.
Tuning Repeatability refers to the wavelength accuracy of returning to a
wavelength after having tuned to a different wavelength.
Reproducibility refers to the amount of wavelength drift which can occur
over the specified time while the optical spectrum analyzer is swept across a
source of known wavelength.
FWHM refers to the Full-Width-Half-Maximum resolutions that are available.
This indicates the width at the half power level of the signal after passing
through the resolution slits.
