As the title says, the quality of the CAN bus is always not very good, but capitalists are not willing to invest in measuring equipment. I would like to ask if there is any economical way to troubleshoot the CAN bus signal quality problem?

The oscilloscope only shows that the quality is poor, the background noise is large, and there are many burrs. It can't analyze the specific problem.
