Tests for Sources

1. Center Wavelength and Spectral Width

To perform this test, you need an Agilent 71450A/B-series optical spectrum
analyzer. These optical spectrum analyzers come with an advanced measure-
ment program which automatically characterizes DFB lasers. Do not modulate
the source during this procedure.
1 Connect the equipment as shown in
Figure 4-1. Center wavelength and spectral width test setup
2 Turn on the Agilent 83400-series source and the optical spectrum analyzer,
and allow them to warm up for 1 hour.
3 Connect the output of the source to the optical spectrum analyzer's input using
a 9 µm fiber-optic cable.
4 On the optical spectrum analyzer, press the AUTO MEAS key.
