How to measure and characterize an MZM modulator?

I need to measure and characterize an MZM modulator.
My main interest is in the following parameters:

  1. Electrical S-parameter
  2. Electro-optical bandwidth OR Modulation Bandwidth OR modulation frequency response m(ω)
  3. Extinction Ratio
  4. Eye Diagram parameters
  5. BER


I currently own an N5227B PNA.


  1. Is there a proposed setup for measuring those parameters?
  2. Is there an application note describing measurement of those parameters?
  3. Can I exploit my already purchased PNA?


Thank for the help.
