Automotive oscilloscopes, also known as automotive diagnostic oscilloscopes or automotive lab scopes, are specialised types of oscilloscopes designed for diagnosing and troubleshooting electrical and electronic systems in vehicles. These oscilloscopes are tailored to the unique challenges and requirements of the automotive industry, where complex electronic systems play a crucial role in the operation and performance of modern vehicles. They can help identify problems in various components and systems, including the engine, transmission, ignition, fuel injection, sensors, wiring, and more.

Modern vehicles use communication buses like CAN (Controller Area Network) and LIN (Local Interconnect Network) for data exchange between various electronic modules. Automotive oscilloscopes can decode and analyse these bus signals.

Automotive oscilloscopes are essential tools for automotive technicians, mechanics, and engineers involved in vehicle diagnostics and repair. They play a vital role in ensuring the proper functioning of vehicle electronics and diagnosing complex electrical issues that can affect performance, safety, and emissions.
