Certainly a vector network analyzer is the next piece of test equipment I need to get. We have several HP 8720 and 8722 where I work, and it's easy to be spoiled...
Unfortunately, that's another quantum leap in cost from the spectrum analyzers and synthesizers I have, at least for those that are microwave capable. I remember a long time ago doing the reverse, taking a TDR plot (or data set) and computing the frequency domain response using FFT. Did I say that was A LONG time ago?
