A passive solution along those lines would be ideal, will try
that before anything more elaborate. Doesn't matter if the
resulting pulse isn't symmetric, I just need it to have stable
shape and timing, and to span several soundcard samples, maybe
10 or 20. If I can stretch the decay to 100uS, that will do.
The T'Bolt seems to have a setup command for everything - except
PPS width!
Thanks,
