PMD measurement is performed after loading of the waveform used for PMD
measurement.
Load the waveform for PMD measurement.
The following explains the structure of, and acquisition procedure for PMD measurement.
Wideband light
source
Polarizer DUT Analyzer AQ6370D
Polarization
controller
1.
Enter measurement conditions so that the entire wavelength range of the
wideband light source is measured. Set the resolution to about 0.050 nm.
2.
Press SWEEP. Next, press the REPEAT soft key. Repeat sweeping begins.
3.
While watching the waveform during repeat sweeping, adjust the polarization
controller so as to maximize the waveform’s peak/bottom difference (the level
difference between the maximum and minimum values).
4.
After the polarization controller has been adjusted, press the SINGLE soft key to
perform a single sweep. Acquisition of measured waveforms is complete.
