Characteristics
and specifications 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 .
Wavelength 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.
Resolution 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.
