Ensuring the receiver component of an automotive Ethernet module or switch meets signal quality requirements and complies with the IEEE automotive Ethernet standard requiring three physical layer electrical tests. These tests include indicated signal quality index (SQI) for the channel, alien crosstalk noise rejection, and bit error rate (BER) verification. Each test maps to the various relevant IEEE and Open Alliance 100/1000BASE-T1 test cases.
For automotive Ethernet receiver compliance, the test setup includes a pulse function arbitrary noise generator, media converter, test fixture, and golden device under test. The test must be set up for repeated runs under various conditions, such as in a climate chamber or when running electromagnetic compatibility (EMC) compliance testing.
