CAN FD serial decoding, force bit rate

Post by Justyn » Wed Jun 19, 2019 2:33 pm

I'm decoding CAN-FD signals with version 6.13.7.707 on Ubuntu, with a 2408B.

The software keeps overriding my selection for the data bit rate. I set it as the correct bit rate, ie 4Mbaud, press okay, then go back and find it has changed it back to another value.

This seems to happen with noisy signals - presumably whatever mechanism it uses to auto detect the bit rate is confused.

I really think it should be possible to override this auto-detection. It's very frustrating, in some cases I'm completely unable to decode the signal because it insists it is at a higher bit rate than it is.
