Analyzing automotive serial buses requires the use of an oscilloscope with serial protocol analysis, symbolic decoding, and segmented memory. Symbolic decoding is used so the oscilloscope can analyze the captured data and decode it into meaningful symbols such as start and stop bits, addresses, data bytes, and acknowledge bits. Segmented memory enables the oscilloscope to ignore unimportant idle time between packets.
Segmented memory optimizes the number of serial packets captured consecutively or selects packets with a particular ID or address. After capture, you can scroll through the frames to identify any anomalies. Additionally, a time-interleaved lister can display two serial buses and correlate data transfers from one bus to another. It is essential to use a differential active probe when probing on differential serial buses such as CAN, CAN FD, and FlexRay.
