John,

First of all you are to be commended for running these experiments.
Without a bit more study of your situation I can't comment too much
but I wanted to throw out a couple of quick ideas.

1) Do you have the VVM probes terminated in 50 ohm?


Yes. They came witht the kit and are called terminators. They are 50 Ohms
each.


2) If you don't have the line stretcher as in Fig 7 of the note, are
you recalibrating at each test frequency?


I do not have the stretcher. I recalibrate at every frequency change.


3) How well is your signal source terminated, in other words do you
know its source match?


I only know that the signal source is an HP 3200B. It directly feeds the
Narda dual directional coupler through a few feet of RG58.


Each of these things can affect the outcome.

More later,


Wes

Thanks, Wes.

John
