@EV , Do you have the Rigol CAN test PCB?
Here is My DS2072 test with FW 00.03.03.01.00,,
I did have problems with trigger setup at 1st but finally it worked ?????

Yes I have Rigol DS6000 Demo Board. The CAN signal is from it.
Teneyes:
If you have a Rigol DG4000 and wish to play with CAN decoding , I have Attached two ".RAF" files that you can load into the DG4000. The Arb function has 66bits , so setting the Arb period to 66us, generates a 1 Mb/s data rate.
Then use the Burst function to Space the Burst of CAN messages.
Below I show a 500Kb/s message (period=132us) that is decoded correctly.
then I show the message with the Burst period set too Small (Fast) and the DSO does not detect the second message start and there are errors. I am not sure what the Spec is for CAN message spacing
The Second file is a message with CRC error

17) There is a visible offset from center position when using AC-coupled Triggers (including filtered LF and HF) at lower time bases (<= 2us/div), as well as serious jitter with certain settings.

As most of EEVBLOGers know, that after Dave Jones (#683) got on Rigol's case about AC-triggering , the Bugs were Fixed :D
