For CAN decode setup see
Controller Area Network (CAN) trigger will trigger on CAN
version 2.0A and 2.0B signals. Setup consists of connecting the
oscilloscope to a CAN signal, using the Settings menu to specify
the event to trigger on, and using the Signals menu to specify the
signal source, baud rate, and sample point.
The oscilloscope will trigger on dominant-low CAN signals. If
you are connecting to the CAN signal using a differential probe,
connect the probe's positive lead to the dominant-low CAN
signal (CAN_L) and connect the negative lead to the
dominant-high CAN signal (CAN_H).
The CAN trigger will trigger on the Start of Frame (SOF) bit of a
data frame. If the N5424A CAN/LIN Automotive Triggering and
Decode option is installed on your oscilloscope, the following
additional CAN trigger types will also be available: Remote
Frame ID (RTR), Data Frame ID (
ID, Data Frame ID and Data, Error Frame, All Errors,
Acknowledge Error, and Overload Frame.
A CAN message frame in CAN_L signal type is shown below:
