Automotive Ethernet Interoperability Tester

The Automotive Ethernet IOP Tester provides an ideal test solution for ECU interoperability testing according to TC8 v1 and TC8 v2 of the OPEN ALLIANCE

The Automotive Ethernet Interoperability (IOP) tester verifies ECUs for interoperability with other ECUs for Layer 1, based on (100BASE-T1/OABR). It offers an open application programming interface (API) and is therefore easy to integrate into existing test systems. Users can create their own tests and test sequences. Measurements of link-up time, signal quality and cable diagnosis belong within the scope of testing.
