Hi Folks:

I'm in the interconnect group where connectors are our thing. I'm the high
speed modeling guy. I take those connector spice models and make sure the
connector will work with our drivers/signal paths/receivers. I have a lot of
experience with connector models made using TDR measurements. I have
recently been sent some models that appear somewhat dubious. The vendor
group that made the measurements says they only use a network analyzer and
then do the inverse fft and some other tricks to get the time domain. They
have some way to fit parameters to a model to get a match to their
measurements. My question is, is the frequency domain method as good as
using the TDR at various edge rates?

Thanks in advance for your comments.
