    How to gerate a pulse it during time is 500 picosecond and one times
    per second?

  3. 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 ?

  10. 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.
