thanks for the information. I will review and try technique out. This is basically a leftover feature I was looking for from using the Fluke 196/199 line that has a circular buffer and always records the last 100 screen.
I was basically looking for that feature on the Picoscope
I am looking for something similar as I can be driving cars for days sometimes with the scope connected to be able to capture intermittent CAN Rx errors (for example stuff bit errors). So if my buffer is always full, whatever I set my time and sample rate too I would need to restart it all the time. That is were my question came from. Now after spending some more time with it, I have a feeling I can probably trigger of such errors to stop the recording. This Picoscope is really feature packed and it seems like it would be capable to this.
Thanks again for your information.
