Re: "Double Pulse Generator"

Gentlemen,
 
Looking back through my stash of vintage test gear, I've uncovered
something which describes itself as a double pulse generator. I'm
going to hook it up to a scope to see what it actually does (if
anything, after all these years). Now I know what a pulse is and what
double means and what a generator does but I've not encountered such a
device before. I'd be interested to learn from anyone who has,
precisely what sort of application this device was intended for? I
would have posted a pic, but hopefully someone will know without me
having to go to the trouble.

I have one made by "Advance", most of the transistors are early
germanium and (I vaguely remember) some avalanche devices to give sharp
pulse edges.   They were exotic specialised equipment used mainly in the
nuclear and telecommunications industries.

As far as I know, their main use was producing pairs of pulses close
together to check that devices like Geiger counters weren't missing
pulses due to latency.  They could also generate test waveforms for
video links.
