The following dialog box will be displayed:
3 Make sure the same measurement channel is selected as
you used for the electrical calibration.
4 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.
5 Select the Measure Mode based on the type of DUT.
• Select Differential for balanced measurements.
• Select Single- End for standard measurements.
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.
