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.

Connect the equipment as shown in

Figure 4-1

Figure 4-1. Center wavelength and spectral width test setup

Turn on the Agilent 83400-series source and the optical spectrum analyzer,
and allow them to warm up for 1 hour.

Connect the output of the source to the optical spectrum analyzer’s input using
a 9

m fiber-optic cable.

On the optical spectrum analyzer, press the

AUTO MEAS

key.
