Applying a Chromatic Dispersion Reference
Applying a Chromatic Dispersion Reference
Chromatic dispersion references can be taken after the results have been
acquired. This is useful if you did not have a source and patchcords at hand
before performing acquisitions (source and Chromatic Dispersion Analyzer
can be many kilometers apart).
Once your reference is taken, you can apply it to your results. The
patchcord and analyzer dispersion will be substracted from your results.
For more information on references and their importance, see Performing
Reference Measurements on page 28.
To apply a chromatic dispersion reference to your results:
1. On the Acquisitions tab, select any line.
2. Click the Apply Current Reference button.

MPORTANT
The reference will be applied to the entire file, not only to the
specific acquisition that is selected.
