Automated Test Applications

AIT provides avionics bus and network interface instruments, software, and engineering expertise to support cost-effective ATE solutions for advanced avionics systems of today ….AND TOMORROW!

Comprehensive Support for High Speed Networks & Legacy Bus Technologies

Depot and Operational level testers must be capable of supporting a wide range of testing capabilities. To accomplish this it is essential that ATE systems are capable of supporting both the latest high speed avionics technologies as well as legacy interfaces which remain relevant as aircraft system life cycles continue to be extended.

Common Avionics Network & Bus Protocols

AIT provides comprehensive support for both the latest and legacy avionics interface technologies with instruments supporting Ethernet (10Mbit/s to 10Gbit/s), ARINC 664, Fibre Channel, MIL-STD-1553, and ARINC 429.

Avionics Instruments for the Latest High Speed ATE Platforms

As the data rates and bandwidth requirements for avionics systems continue to increase, the test engineers challenge of designing ATE to support the demands of today, and tomorrow at a reasonable cost becomes increasingly difficult.

The ATE systems of today require:

  • Accurate data logging with precise time-stamping (with sub u-Sec precision)
  • Time synchronization across instruments and subsystem chassis
  • High Bandwidth back-planes
  • Instrument adaptability to support the protocols of today AND tomorrow.

To meet these requirements, ATE designers are increasingly turning to PXI Express based platforms, and we are ready to support this with a wide range of avionics network and bus test instruments for PXI Express.
