Tester integrated into military ATE
system
Teradyne's Assembly Test Division has completed the integration of its powerful and flexible M910 digital test instrument into the Marconi Selenia Communications general-purpose ATE platform.
Teradyne's Assembly Test Division has completed the integration of its powerful and flexible M910 digital test instrument (DTI) into the Marconi Selenia Communications general purpose automatic test equipment (GPATE) platform The project is part of Marconi Selenia Communications' development of test engineering support for military/aerospace programmes including the Typhoon and Tornado fighter jets, and NH90 Helicopter

Software environment speeds test program debug
New from Teradyne, Debug Pro is a user-friendly software debug environment for TestStation ICT equipment.
Marconi Selenia Communications began evaluation of Teradyne's M910 DTI about two years ago, while seeking a flexible solution capable of responding to its rigorous digital test requirements.
The first application of the new system will be on the Canadian Air Force EH101 Helicopter.
The GPATE platform developed by Marconi Selenia Communications is based on flexible architecture, and designed for easy reconfiguration and upgrading to cope with variances in product test requirements and field conditions.

For example, as used in the NH90 helicopter, the GPATE system can be configured to test as many as 60 of the line replaceable units (LRUs), a term used to describe the "black boxes" which contain the various communication and control systems onboard the aircraft.
Teradyne's M910 DTI is an important component within this system.
Integration of the Teradyne DTI technology into the GPATE system required a collaborative effort between Teradyne and Marconi Selenia Communications, and a significant development contribution from Teradyne's local test specialist, Test Technologies, of Milan, Italy.
"We chose to integrate an existing digital test instrument rather than develop our own, which gave us considerable development savings", said Mattia Lugari, Avionic Test Systems R and D Manager at Marconi Selenia Communications.
"The collaboration with Teradyne and Test Technologies was also important for developing and increasing our knowledge.
The challenge to create a software interface that would link the high-level Atlas test development environment (from TYX) with Teradyne's digital drivers required significant work on timing and translation functions.
The result is impressive, we now have the ability to emulate a synchronous serial interface electronically compatible with RS422, with the ability to test a wide range of avionic busses - often with nonstandard protocols and timing requirements - with a single test solution".
"Power and flexibility are what first attracted Marconi Selenia Communications to the M910 DTI, but the widespread usage of this unit in mil/aero programs across the globe is what cemented their decision", said Carl Rosenblatt, Business Unit Manager, Military and Aerospace Test Solutions, Assembly Test Division.
"The adoption of the M910 DTI solution has given Marconi Selenia Communications access to a broadly accepted technology that can be leveraged internationally for use on both legacy and new programs for years to come".
Teradyne's M9-Series DTI consists of versatile C-size VXI instruments for high-performance digital testing, and powerful, open software that is easily updated to prevent obsolescence.
Its VXI plug and play software driver and hardware are compliant with VXI interface standards, and allow the M9-Series instruments to integrate easily with other instruments in VXI-based test systems.
