Before such designs can hit the road, intensive testing is needed. During the Automotive Testing Expo this week, Rohde & Schwarz showcased a compliance test software for BroadR-Reach Ethernet, utilising the company's RTO oscilloscope.
With the RTO-K24 compliance test software, users can conduct automated testing of such interfaces according to the specifications of the OPEN Alliance which drives the development of the BroadR-Reach technology. BroadR-Reach allows aggregating multiple applications such as video streams generated by back-up cameras and the distance-warning radar signals in a single, open and scalable Ethernet network inside the vehicle.
RTO's high measurement dynamics of more than 7 effective bits (ENOBs) provides reliable measurement results even in specified tests with interfering signals, enabling users to assess and check their products during type tests or end-of-line production tests. The signal quality of the Ethernet interface can be verified, for example, by means of drop-out tests which is used to review the signal waveform of the BroadR-Reach data telegram. The system offers graphical display options that support the user conducting the measurement step by step. Configurations can be generated automatically; the results are provided in a clearly arranged protocol.
