Current products do not support differential inputs natively. To decode differential protocols today (such as CAN), signals need to be hooked up a certain way via the guidelines below:

It would be nice if next-gen hardware natively supported differential inputs, potentially via proper differential probes.

Do we have an update on this? We have been requesting differential support for a while
Tim
Thanks for following up on this. This is something we're considering for next-gen hardware, however, we don't have any other updates for now besides that.

"For the future an official adapter board would be great. Using voltage divider, or a more sufisticated board might provide active amplifiers and/or methods differential signal analysis"

"So if we are wish listing here: differential inputs (completely fixes CAN and other similar stuff), input attenuation (to extend the analog input range - 20V would be good, 50V would be great)."
