John, I'm impressed. That really does do the trick, doesn't it? I've
wondered about that ever since they said to use coax for a pulse
thing.

Kewl!

Thanks!

Hello, this is a very simple circuit. How does the coax cable produce
picosecond pulse ?

What Voltage?

Maybe a triggered Avalance Pulser would do the job.

Figure 8 shows a sophisticated version from an
Avalance Pulse Generator, there are some more simpler versions
in some LT-Applications by Jim Williams.
