Hi Bob, That is the issue, it doesn't. (the 2,3 different types I would like to use none of them have it, so I will be making a small pcb with the trimpot and the regulator and some capacitors etc). Luis Cupido. ct1dmk On 1/7/2015 1:09 AM, Bob Stewart wrote: Does your oscillator have a VRef

Many thanks to all for the nice tips. I may narrow down by saying a few more specs as suggested. The pulse would see a somehow unknown load but for a start I was suggested to have my source with 50ohm impedance so worst case would be a short circuit and therefore the pulse would be a current

. That being the case hardly has any solution whatever USB interface implementation... except with a real LPT. The stuff I've used was kind of asynchronous spi etc. I had zero issues with that.
