"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.
