We dont have to start it all over, it is not possible for my case. My shaft encoder ist constantly, fast turning, please show me a video where you constantly, exactly count the edges for an hour. The Rigol have a simple button "Count Edges" and it counts, and counts, and counts until I stop it, that...

Sorry Gerry it wasn't precise, you can count edges, but in my case it is either counting exactly but resetting the counter so fast that I can't use it or if I change the timebase that I have enough time to see what the counter counts it will miss a lot of edges. So in my case it is unusable. You sho...

No they don't extend their software. I ended with another oszi that is able to count edges.

Well Ok it looks like it is not really possible to have a sum of edges, maybe you can extend the picosscope software to have a checkbox for that in the measurement options for counting edges. Meanwhile I take the SDK and try to wrote my own code to count all edges. Problem not really solved , but I ...

@Martyn: Are there any known Limits ? My smallest try was 384 KB, which did'nt work

Thanks, I did and it works but not perfect, if I turn the shaft Encoder faster there is a kind of overflow. See Picture. This happens more often if go to 5s/div. Overflow Offtopic: Somehow the img-tag is not working it always says ...

Maybe this makes it clearer:
EdgeCntPicture
EdgeCntVideo

Ok, in my case it is switching to slow mode at 200ms/div but still the count resets with 50ms/div.
I made a short Video, see attachment.

Hello, i have a picoscope 2000 and want to check a shaft encoder. For that I add a measure of type "count falling edges", channel A, whole trace. When I choose a Collection time of 100ms/div I have a nice view of my edges, the Count is correct but when the "ray" reaches the right end and start again...
