Magnus can you elaborate on the SR-620 performance? In my hands the 53230A with a spec of 20ps single-shot does about 11-13 ps RMS for a 1PPS TI-measurement between CH1 and CH2 - so in theory a single channel is 1/sqrt(2) better than that. In what measurements would an SR-620 be better? The 53230A does have a design-flaw where one of the input BNCs has a very narrow PCB-trace which tends to break. I think I've fixed 2 or 3 counters with that same fault.
