A2B® Component Tester
AUTOMOTIVE AUDIO BUS PRODUCT TESTING
A2B®-Component-Tester
Precise testing and simulation of A2B® -networks
The Automotive Audio Bus (A²B®) is a bus developed by Analog Devices Inc. for infotainment systems in automobiles. It is increasingly being used in other applications such as AV conferencing systems. Typical A²B® -products are Hi-Fi amplifiers/speakers, head units, eCall systems, microphones, vibration/noise suppression units, actuators, or sensors
Communication happens via a simple two-wire UTP (Unshielded Twist Pair) cable. All A²B® -components are connected in a master/slave architecture to form a network. The complexity of audio systems in these A²B® -networks is reduced, and with it the cost and weight.
We have developed an innovative solution for easy testing of these structures: The NOFFZ Infotainment Test Device – ITD 1024. The device tests all A2B® -signals and communications comprehensively and extremely reliably. You can use the ITD 1024 during the development phase or for validation and in production.
Our A2B® -test assortment is rounded off by our Line Test Box – LTB 1024. This innovative device can measure the bus voltage and current between two A2B® -nodes during bus operation, simulate fault insertion on both A2B® -lines, and perform load simulation.
THIS IS WHAT DISTINGUISHES THE A2B® -BUS
