Fair enough.  

Here's a techie question:

I have a really neat high voltage "video input" circuit from an old HP piece
of test equipment.  There are two large capacitors and a cascade of
resistors and a diode between them.  Essentially, it converts a high
potential to a low potential.  What I want to do is use this circuit as an E
field detector.

I have a DATAQ DI-148U acquistion module, which I would like to wire the
circuit output to.  My question is simple.  If I place a probe near the high
potential resonator of the coil and another probe a given distance out, and
connect one probe to each of the capacitors on the board, will I have a
reliable measurement of the E field?  If so, how can I position the probes
and calibrate this device to give a meaningful reading?
