I've also used the Eval boards from Maxim or Nat Semi, but these day's they're
usually USB. Sometimes, the protocol isn't published, but is trivially reverse

Many sources and papers refer to the actual DMTD mixer system (and
zero-crossing detector etc.). But, I've seen very little on the phase

I'm looking for some amplifiers with adjustable gain (say from 0 to 5) and
offset (say +/- 5V) for general benchtop use (e.g. you have some widget you
want to test as a replacement, but the original device had different input
ranges, and before you go redesign the rest of the circuit..) with at

Hey Chuck, I just learnt a new word: Gonzo :-)
I has a nice feel to it -- out of interest do you have the etymology? I

Does it have any implied meaning other than that which I inferred: i.e.
idiotic?

Not that much simpler..
You still have the Basic List and Munitions list, and the terms on the list are
vague enough
The issue of returning equipment for repair is a significant concern. Unless
you have the appropriate licenses both ways.. Company A in Germany, say,
ships a widget to company B in the US, all nicely approved by whoever in
