Which Yokogawa Oscilloscopes Support CAN Bus Symbolic Decoding?

Resources:

Over the past 30 years, the development of in-vehicle networks (IVNs) and the CAN bus has been driven by the need for more efficient, reliable, and scalable in-vehicle communication systems. From the early proprietary networks to the sophisticated, multi-protocol architectures of today, IVNs have played a crucial role in the evolution of automotive technology, with CAN bus remaining a cornerstone of this development.

Oscilloscopes & CAN Bus Decoding: Essential Troubleshooting

Oscilloscopes are traditionally used to monitor and troubleshoot waveforms by visualizing electrical signals over time, helping identify issues like noise and distortion. Recently, they have gained functionality to interpret digital waveforms and decode payload signals. Modern oscilloscopes can decode protocols like CAN bus, turning electrical pulses into readable data frames. This enables engineers to monitor signal integrity and understand transmitted data, ensuring proper configuration and troubleshooting of in-vehicle networks.

Yokogawa Oscilloscopes that Support CAN Bus Decoding

The DLM series oscilloscopes (DLM5000HD, DLM5000, and DLM3000) and ScopeCorders (DL950, DL350) provide the CAN Bus symbolic decode analysis function.

Both instrument families support symbolic decoding to table form and exporting the decoded data to CSV. In addition, DLM series oscilloscopes have an overlay function when zoomed into individual CAN packets. The overlay function displays the CAN packet structure directly below the time domain waveform. Please see the attached screen shots for examples of the DLM and ScopeCorder CAN bus analysis.
