All-states measurement method for PDL and PER with synchronous scrambler

Posted: 17 Aug 2012 ?? ?Print Version ?Bookmark and Share

Keywords:synchronous scrambler? polarization? synchronization triggers?

The implementation of the all-states PDL method described in this note makes use of the characteristics of the Agilent N7785B synchronous scrambler, which can be programmed for repeatable stepping through a sequence of polarization states at high speed while producing synchronization triggers. This can be used to shorten total measurement time, allow optimized detector averaging times, and normalize the results to remove the polarization dependence of the setup from the results, delivering average insertion loss (IL) at the same time.
