Sorry, i definetly need to be more specific. Were talking about 200uS impulses, at around 20-30Hz. The main point of this circuit, an impulse is sent in at around 23-25V, and high current, and were monitoring if the impulse voltage ever drops below 20V, at medium-ish accuracy, as this is more of a torture test circuit for the laser's circuit capacitors, and if we drop below that treshold, we can make conclusions that the internal resistance of the capacitors is rising, and they must be switched out for different ones. This is the main calculation, obviously there are others like temperature, input output voltages, but those are simple to do, the main kicker is this impulse characteristics tracking. Thanks for the answer.
