Let me describe my application. I'm building a Marx-like impulse generator that will (hopefully) generate a 100A 2nsec impulse in a 15nH coil. I'd like to probe the voltage on the inductor directly. Barring that, I could use a weakly coupled pickup coil. My scope is a 54855A. I'd like about 10 points on the pulse.
What's the best way to probe this without corrupting the pulse or killing the scope?

the scope only ahs a 50 Ohm termiantion, and msot current probes want a 1MOhm termiantion. so... if going witha 1M Ohm trmianted current probe -> the E2697A High impedance adapter, whcih ahs 500 MHZ of bw, which should get you 2 ns Tr.
However Agilent does not currently offer a current probe with more than 100 MHz bw, no pun intended. Even then, that probe can hadle only 50A peak.
So... find a current probe on google with:
sufficient rise time (200 MHz should do it, if it exists
