The PM8000 has a default framework for calculating pulse rate and showing the peak rate. What is the maximum rate we can expect out of this in terms of hardware and firmware limitations?
(To put it in context, we want to sample at high speed pulse ~6000kHz and log the count frequency at a much slower speed, maybe 0.5s, do we need to look elsewhere or is there a way we can do this with the PM8000?).
Looking at the onboard digital input specifications in the PM8000 user manual:
Pulse frequency ≤ 25 Hz
Event timestamp accuracy ± 1 ms
Response time 20 ms
Minimum pulse width 20 ms
Hope this helps,
