I used to tune them that way also, and thought I
did well, but after I got access to a Spectrum Analyzer with tracking generator,
I find it much easier and more accurate. Maybe because the pattern is
visual when you are tuning with the tracking generator and analyzer. I've
taken duplexers I tuned the old way and put them on the service monitor and
found I could get 8 or 10 db better with the analyzer. You use what you
have, and I sure would use the analyzer/generator combination if I had
it.

Analyzer
I have always tuned duplexers just using a signal
generator and a radio receiver. Peaking the passband and then going for the
deepest notch for the reject. Although this seems to work, the results haven't
been spectacular. I realize that there are many variables to consider. My
question is, does using a spectrum analyzer and a sweep generator ( I am
guessing here) make the process better, and if it does, how so ie what is the
principle behind it?
Thanks
