Characteristics The distinction between specifications and characteristics is described as fol- and specifications 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. |
| 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 refers to the |
| This indicates the width at half power level of the signal after passing through |
| the resolution slits. |
