Operating the Polarization Mode Dispersion Analyzer

Polarization Mode Dispersion Analyzer 41

Performing a Null Measurement

This feature allows you to perform an offset nulling of your FTB-5500B

Polarization Mode Dispersion Analyzer. During this operation, no light

should reach the detector port of the Polarization Mode Dispersion

Analyzer.

The very first time you insert an FTB-5500B Polarization Mode Dispersion

Analyzer into the FTB-500, the application will prompt you for a nulling.

EXFO recommends that you perform a null measurement just before

verifying the input power level to ensure the accuracy of the displayed

level.

To perform a null measurement:

1. From the main window, click the Parameters tab. Click Nulling and

follow the on-screen instructions.

2. When nulling is complete, click Close.
