I'm curious if anyone in the group has tried using an ESD verification
target mounted on aluminum foil faced foam rather than a serious piece
of sheet metal? My thought is that at the FFT frequencies of rise-time
and decay, the skin depth is going to be less than the thickness of the
foil, so
Back in the day, when a GHz scope with a Polaroid camera was required to
catch one discharge, I did collect a spectrum of ESD discharges. I used a
KeyTek simualtor set on repetitive fast discharge, and put the spectrum
analyzer on max hold. Over some minutes, the spectrum filled in with each
disc
sion may or may not be the problem.

HI Ralph,
Nice "out of the box" thinking, however, I suspect spectrum analyzers
in those earlier days would have had issues in capturing all
components of the frequency spectrum of a pulsed signal. Just a guess,
though.
