Physical layer electrical tests for automotive Ethernet transmitter compliance involve executing a wide range of conformance tests based on different data rates and standards. Two standards governing bodies for automotive Ethernet, the IEEE, and the OPEN Alliance, specify a wide range of these conformance tests and test cases.
Performing the automotive Ethernet conformance test requires an oscilloscope. A network analyzer and an arbitrary waveform generator (AWG) or function generator are used for transmitter distortion for 100 Mbps and 1 Gbps tests, MDI return loss, MDI mode conversion loss, and power spectral density (PSD) tests. In addition to measurement data, a wide range of electrical tests must be performed to obtain a margin analysis report showing how closely each automotive Ethernet device passed or failed each test.
