The last one is just a re-print of the old stuff - I don't know how stuff
like this gets published in MTT.

> Hi I have an interesting problem regarding some TDR analysis that I am
> curently undertaking. I am still investigating the impedance's changes
> that occur between stripline, and microstrip geometry's, and I wish to
> thank everyone for there help, it has been very useful.=20
> The background to my current problem:
> I inject the TDR signal through a lemo connector onto a small length of
> microstrip, then down through a via into stripline. Because the
> microstrip section of track is so short, the impedance change between i=
t
> and the stripline, are lost in the noise of the lemo connector.
> My question is how to best analyse the section of track after the via,
> as I have the lost information of the preceding impedance change.
> Preceding impedance, and the amplitude of the propagating wave, are the
> two variables that are used to calculate the impedance of a section of
> track. Is it possible to use TRD to analyse a section of track after a
> "hidden" impedance change.
