I’m looking for a circuit or Gizmo that will generate a 10-100 nanosecond 1-2volt pulse into a standard 50 ohm coax connector and load. These pulses should be rounded, not square. The pulses would be individually triggered by an Arduino pin on the rising edge. The timing of the Arduino pulses will be pseudo-random. The width of the Arduino pulses should be irrelevant to the output pulse.
We have pulse & signal generators but they do to much. We need a minimalist circuit as described. I searched ebay but every generator does too much and gets in the way.
I am writing software for high-energy neutron physics experiments. The software gathers data from gamma ray detectors and high speed A/D equipment. I have no control over availability of the neutron beam (very, VERY expensive!). A few random hours twice a month is inadequate for software development. The A/D system has coax input and expects fast 1-2 volt pulses. Generating simulated neutron/gamma ray events from an Arduino would greatly speed software development and debugging.
You might think people around here would know how to do this. But everybody buys fancy expensive gear and knowledge of basic logic/electronics has atrophied. Three cheers for the Maker revolution!
Any help would be greatly appreciated.
