Marc, > ...preferrably an atomic clock that I can hook....
if you need the stability and precision of an atomic clock you will of course not come around to REALLY use one! However, for everything else I would do it like that: Generate a 14.318 MHz signal phase locked or DDS synthesized from the atomic standard and feed this signal directly into the motherboard. Every motherboard features timers that can be read out regardless of operating system and preferred programming language that are clocked by this 14.318 MHz signal. You will save lots of expenses that an otherwise hardware based low latency clock may cost. > I am looking for used equipment, it should fit in a hobbyists > budget, sth. in the 1000-5000$ range would be nice, but it > should be as precise as possible. Most interesting note from Switzerland! Is this your weekly or monthly hobbyist budget?
