Most of the requirements for higher data rates stem from sensors like cameras around the car, 5G Telematic units (TCUs) 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 5.6GHz. The Open Alliance TC15 PMA compliance test specification addressing this standard is still in a draft state.
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 is easy to use offering guided tests and a very comprehensive report.
Rohde & Schwarz has announced that it now 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 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.
The R&S RTO-K88 and RTP-K88 compliance test software options for MultiGBASE-T1 are now available from Rohde & Schwarz.
