As nations worldwide are vigorously developing renewable energy technologies today, industries have shown clear trends shifting toward intelligent, digital, networked, and energy-efficient solutions. With the growing functionality of electronic products, various bus protocols have emerged to meet the increasing demand for inter-device communication. Common protocols include I²C, CAN, LIN, FlexRay, CAN FD, SENT, and USB. These protocols enable efficient data exchange between different devices, facilitating seamless system coordination. The rapid advancement of technology keeps increasing both the variety and complexity of bus protocols. Bus triggering and decoding is a key feature of an oscilloscope. It analyzes communication protocols across different bus systems and supports corresponding testing, debugging, and fault diagnosis, driving the industry toward smarter, more efficient, and sustainable development.
