Making E/O measurements

Agilent N4373A Lightwave Component Analyzer, First Edition
3 Make sure the same measurement channel is selected as
you used for the electrical calibration.
4 If you are using an adaptor to connect a device with an
output with 75 Ω impedance to the 50 Ω input of the
ENA, please check the box here.
5 Select the wavelength at which you are testing. This
should be the same as the wavelength selected on the
front panel of the optical test set.
6 If you are connecting an optical attenuator to the photo-
diode input of the Lightwave Component Analyzer, enter
the amount of attenuation for PD[dB], in dB.
• For more accurate measurements, include the
attenuator in the test circuit when calibrating the E/O
measurement.
The measurement results will be displayed on the screen
after correction using calculations based on photonic
attenuator insertion.
7 Click on the [Start] button to start the measurement
preparation.
8 When the message box is displayed, click the [OK] button
to start the measurement.
You can now connect your
device under test.
The measurement begins
automatically.
Please refer to the user
guide and online help of
the network analyzer for
further information on
measuring.
