In vehicle networks and ECU testing

Automotive Ethernet and other bus systems

Inside a typical car, you will find over 100 electronic control units (ECU) controlling everything from brakes, transmission, engine, A/C, steering, cameras, radar, acoustic sensors to the non-cellular and cellular wireless communications.

ECUs talk to each other via car buses, including controller area network (CAN), media oriented systems transport (MOST), local interconnect network (LIN) and FlexRay.

Automotive OEMs and Tier 1s are moving away from mixing so many different bus types to something more uniform, enabling higher data throughput, lower latency and less weight in order to reduce complexibility and increase cost-efficiency.

Rohde & Schwarz offers state-of-the-art testing solutions:

Trigger and decode capability for CAN, CAN-FD, LIN, FlexRay, CXPI and SENT
Compliance tests for automotive Ethernet (100BASE-T1, 1000BASE-T1, 2.5GBASE-T1)
EMI debugging capability

Product information

R&S®RT-ZF8 automotive Ethernet compliance fixture

The RT-ZF8 fixture provides all necessary connections for testing the physical layer of automotive Ethernet standards 100BASE-T1 and 1000BASE-T1

The fixture is used in combination with the R&S®RTO and R&S®RTP oscilloscopes, the R&S®ScopeSuite software and automotive Ethernet options (R&S®RTO-K24, R&S®RTP-K24, R&S®RTO-K87, R&S®RTP-K87).

R&S®RT-ZF7 automotive Ethernet trigger and decode fixture

The RT-ZF7 fixture is intended to be used for probing an automotive Ethernet signal (e.g. 100BASE-T1 or 1000BASE-T1). Full duplex connections can be probed on separated directions.

The fixture is used in combination with the R&S®RTO and R&S®RTP oscilloscopes and automotive Ethernet options (R&S®RTO-K57 and R&S®RTP-K57).

R&S®RT-ZF7A SMA adapter

Fully compliant with the adapter specification of the OPEN Alliance Automotive Ethernet ECU Test Specification (version 2.0)

The main intended use case is to connect a twisted pair automotive Ethernet cable to SMA.

Dr. Nik Dimitrakopoulos, Market Segment Manager Automotive

"Modern cars typically have more than 100 electronic control units (ECU) connected via different in-vehicle bus networks. These buses are used to exchange information and coordinate control. Autonomous driving technology creates a demand for much higher data rate traffic within in-vehicle communication systems. Today, we are talking about 100/1000BASE-T1. Tomorrow, it will be multi-gig speeds. To verify the functionality and quality of these data streams, automotive engineers need to be able to search for specific signals, trigger, decode, measure crosstalk and perform compliance testing."

Dr. Ernst Flemming, Director of Product Management for oscilloscopes, Rohde & Schwarz

"Automotive Ethernet is now widely introduced in cars. In the OPEN Alliance, the industry has defined specific compliance tests. We offer a complete compliance test solution for 100BASE-T1 and 1000BASE-T1 that is widely accepted by OEMs, Tier 1s and test houses. With the new triggering and decoding solution for 100BASE-T1, automotive Ethernet can now be debugged the same way as the traditional CAN bus."
