[SI-LIST] : revised 1GHz probe plans

Hi All,

First, I have to apologize for a couple of replies that accidently
went to the whole group instead of the intended person. I was very
careful, but it happened anyway. It's cut and paste from now on!

I have added a theory of operation section to the 1 GHz probe plans on
my site at:


The section discusses why the foil is needed and the underlying
limitation on the useful frequency range of the probe. Also added is
the ability to click on the probe pictures to blow them up to full
screen size, instantly. You can even clearly read the values on the
surface mount resistors!

I am interested in any comments on the theory addition (correctness,
readability, etc.)

Also posted is the discussion on this month's problem of how to
measure circuit voltages with a paper clip.

Thanks in advance,
