Not quite but close. You will need a DSO-style scope that can help you look at the signals and do some analysis on them with looking for noise.
I actually think a better idea would be to use some of the tools now available via Linux for looking at the CAN bus for timeouts and retransmits (I believe you can do this on the RoboRIO in code too). I suspect you're going to see more errors with a star topology.
We actually have a scope that can do this and if I had time then I'd like to but I don't honestly have the time to dig into it. If there is a team in NC that wants to do it then I'll volunteer the scope for the research but they would need to come out to our space to use it and bring the necessary test setups with them.
