John:It seems to me this is a bit one-sided.
Could you please describe the test set up YOU use to make measurements on AUDIO equipment?
I know you work on a lot of very exotic projects at work, but I'm curious how much of that transfers over to actual hands-on work with audio gear. If you get to use the facilities of the national lab for making audio measurements, then you're a very lucky guy. Perhaps you would like to duplicate John's set up, and report on your results?
It's easy:
Set up low distortion oscillator feeding a distortion analyzer via the DUT. Use analyzer to null out the fundamental. Take output of analyzer and view on a spectrum analyzer. Look at harmonics of fundamental. Simple.
Since you could clearly set this up with a lot more care than JC, given your far greater expertise, this should be child's play for you.
I am also setting up a similar environment to examine the same thing. Which one of us will have some real results first?
