Default Re: Philips PM5509 TV Pattern Generators

With Philips test equipment the /00 number represents the revision version of the unit. In the case of your PM5509's, one is a revision 2 and the other a revision 5.
There appears to have been a large number of changes internally as the revisions occurred and documentation for these revisions is not easy to find.
