Hi Grant
Couple of thoughts here :-
1) A 'real' TDR measurement would require a pulse generator with a fast
rise/fall time. The faster the rise/fall, the better.
Yes, I suspect it needs a pretty decent TDR for this.
They are available in much more affordable pricing than comparable VNA
options, and with much less calibration hazzle for OK-ish results.
What is lacking, to my knowledge, is free post-processing software. I
haven't looked around in ages. Maybe it is time to do a search again.
Cheers,
Magnus
