Short answer is "north"! All the good fet probe circuits are in the
north.


Try to be less descriptive of your requirements. I'm overwhelmed
by all the details.

Good?
Probe What?
Bandwidth?
IF by single rail, you mean single power supply,
you're gonna have to jump thru hoops if you expect to measure
bipolar signals. Unless your requirements are very restricted, and so
far we can't know that, you'll be
far better off to bite the bullet and use bipolar supplies.

Hi Wayne,

I've not built it but Elektor Electronics did publish a construction project
for one , perhaps if you build it you could post if it is any good!

It's online. You can get to it by searching the Elektor site, but I'll save
