A²B® Audio Bus Testing Service

The UNH-IOL is the first test lab for A²B® conformance testing, a low-latency digital audio bus that transmits audio and control data together with clock and power over a single unshielded twisted pair cable. This capability reduces cable weight and system complexity while improving fuel efficiency. 

We offer conformance and interoperability testing for A²B Modules. A Module under test could be a prototype development board, a finished ECU for a target architecture, or the full configuration desired for validation by an OEM. These services were built through our partnership with Analog Devices to support the emerging ecosystem of A²B solutions.

Test Services Include:

• Node-level Modules 
  • Conformance tests per the A²B requirements
• Interoperability 
  • Tests against a reference testbed of solutions.
• Networks 
  • Validation of a full system of interest to a customer (eg: an OEM)
• Signal Integrity 
  • Analog PHY validation

OEMs and A²B solution providers are encouraged to work with us for neutral, confidential, third-party testing for validation of A²B solutions, whether in the early or final stages.

In addition, we offer several testing services for the automotive industry including Automotive Ethernet, Time Sensitive Networking (TSN) Automotive Networking, and Avnu Certification.
