Pulse Head

Palinurus · 2009-02-06T12:13:30+00:00

I have need to generate an extremely fast pulse to characterize the rise time of oscilloscopes, and am disinclined (read "unable") to spend the $Ks to buy a full-fledged scope calibrator. I notice that there are occasionally tunnel diode pulse heads available used or surplus, but nobody seems to know what kind of drive signal they require. One Tek part currently on eBay, 067-0681-01, even Tektronix seems to know nothing about. (Thanks a lot, Tek.) Is any information available? I wouldn't be averse to building one, if I had a reliable design.

- That avalanche pulser looks doable. I seem to recall building such a thing several years ago, to drive a single heterojunction laser. It used a 2N2222.
