K88 enables compliance testing on next evolution of automotive ethernet standard

The K88 option for R&S RTO and R&S RTP oscilloscopes from Rohde & Schwarz enables compliance testing on the next evolution of the automotive ethernet standard. The new IEEE 802.3ch standard addresses the need for high-speed networking and data transfers within the car.

With the new K88 option, R&S RTO and R&S RTP oscilloscopes now offer a full transmitter compliance solution for MultiGbase-T1 based on the IEEE802.3ch spec for the PHY layer (layer 1). The solution comes in a modern user interface and, says the company, is easy to use offering guided tests and a comprehensive report.

Most of the requirements for higher data rates stem from sensors such as cameras around the car, 5G telematic units and networking backbones for multiple domain controllers. MultiGbase-T1 ethernet standard meets these needs by including 2.5G, 5G and 10G speeds. Compared to 1000Base-T1, MultiGbase-T1 uses PAM4 (4 levels) modulation with symbol rates of 1.4, 2.8 and 5.6 GHz. The Open Alliance TC15 PMA compliance test specification addressing this standard is still in a draft state.

Rohde & Schwarz offers a complete automotive ethernet compliance test solution including using a vector network analyser such as the R&S ZND for MDI return loss measurements.

Control of the measuring instruments, calculation of the results and documentation can be automated with the R&S ScopeSuite test software. A test wizard guides the user step by step through the test procedure with illustrated instructions. Automatic test sequences allow for a fast, reliable test execution and help minimise the probability for user error. A configurable test report documents the test results.

R&S ScopeSuite is a standalone application that can run on the oscilloscope or a separate PC.

As a leading global supplier of test and measurement software, instruments and systems, Rohde & Schwarz applies its technical expertise to develop innovative solutions through the entire automotive lifecycle from pre-development to production.
