This Tektronix handbook introduces automotive Ethernet and other vehicle bus standards, and explains testing methods to ensure performance and compliance.
The handbook provides an overview of automotive Ethernet and legacy bus standards such as CAN, LIN, FlexRay, MOST and SENT, describing their data rates and typical applications in modern vehicles. It discusses the growing data demands of vehicle networks and the need for higher‑speed, low‑latency communication.
It also outlines the main testing challenges—including parallel bus debugging, electrical consistency, protocol compliance, and signal‑integrity analysis—and presents Tektronix’s measurement solutions, such as high‑bandwidth oscilloscopes, protocol‑decode options, and non‑invasive signal isolation for automotive Ethernet testing. This manual is written in Chinese.
| CAN (low‑speed) max data rate | 125 Kbps |
|---|---|
| CAN‑FD max data rate | 5 Mbps |
| FlexRay max data rate | 10 Mbps |
| LIN max data rate | 20 Kbps |
| MOST max data rate | 25/50/150 Mbps |
| Automotive Ethernet (100BASE‑T1 / 1000BASE‑T1) | 100/1000BASE‑T1 |
The handbook covers CAN, LIN, FlexRay, MOST and SENT as the primary vehicle bus standards.
Key challenges include parallel testing of multiple buses, debugging bus issues, ensuring electrical consistency, and verifying protocol compliance and signal integrity.
Tektronix recommends high‑bandwidth oscilloscopes with protocol‑decode options, non‑invasive signal isolation, and appropriate probes and fixtures for Ethernet, CAN, LIN, FlexRay and SENT testing.
