Setting Up Your Chromatic

Dispersion Analyzer

The parameters you set will be kept in memory after turning off the
FTB-400 Universal Test System.

Setting the Wavelength Range

You can set the wavelength range within which you want to perform your
acquisitions. You can work with predefined bands (C, L or C+L) or set the
wavelength range by using the custom option. This option could be useful
to perform acquisitions in a specific area of a band or between two bands.

To select a predefined wavelength range:
On the Parameters tab, use the Range dial.

To set the wavelength range using the custom option:
1.
On the Parameters tab, set the Range dial to Custom.

2. Enter your values in the From: and To: fields. The values you enter

must be between 1530 and 1625 nm, which are, respectively, the lower
limit of the C band and the upper limit of the L band.
