Although this is not a feature unique to Pico, here are a couple of animations that demonstrate how the Maths channels can be used to help with CAN signal analysis. Often signals can look less than ideal & it can lead to some doubt about if whether the data packets are intact or corrupt or not.

This is probably old news to experienced scope users, but I thought it might be useful.

Good Tip Dave.
If possible, could you upload the psdata file showing the CAN error?

Thanks,

Thanks dave, great technique. I'm still learning on the pico everytime I use it. what would we expect to see data wise if we decoded the can message (where the fault is)
