Improving Pilot Display Unit (PDU) testing

Amfax delivers a new generic ATE for testing aerospace pilot display unit modules. The system enables testing of all module types using the same tester

---

Amfax have recently designed, built and delivered core PXI based automated test systems to a major aerospace manufacturer. The brief was to come up with a design that could test all the pilots display unit (PDU) modules using a single automated tester. Previously the client had a number of ATE's that each tested just one module. This meant that previously the client not only had to invest in multiple testers but had to obtain support for each unit separately. The ATE used a fully loaded PXI rack to house all of the instrumentation needed to ensure test coverage of all the measurements required for each module. The modules tested included a solar cell, electronic display, interface unit and auxiliary PCBs.

System benefits:

• The test system was easy to use by the operators. This was achieved by careful design of the GUI
• The client could take up ownership easily to due the modular nature of the system
• The self test fixture enables easy and regular maintenance of the system
• Modular design enables easy repeat system build

System features:

• PXI based instrumentation
• Wire free multi-interconnects using MAC Panel Scout interface
• Safety interlocks on cabinet to comply with stringent health and safety requirements
• Fully CE Certified
• Supplied by AS-9100 aerospace approved supplier
