LabWindows/LabVIEW/TestStand/VeriStand based ATE
Accord has in-depth experience in designing and developing Lab View/Lab Windows and NI PXI Ballard or custom hardware based ATE systems for specific applications. Mechanical designs of the ATE Systems have also been undertaken by Accord. Multiple Test Systems have been designed and used in FAA and CEMILAC Certification of LRUs.
Chassis and Instruments
A typical ATE includes Chassis and Instruments. Accord provides rack development solutions based on the client’s requirements. Accord performs an analysis of the client’s requirements based on which the appropriate COTS hardware is selected and design recommendations are made. Accord always procures and integrates instruments from reliable and approved vendors.
In addition, Accord delivers customized solutions in situations where Standard Instruments do not meet the requirements (e.g. Signal Conditioning Units and Power Distributions Units).
In addition to Instrument selection, Customization, and Chassis development, Accord takes care of Assembly and Wiring utilizing experienced In-house Production teams.
Accord is experienced in developing Full or Half Size chassis Solutions.
Test Fixture Solutions
Accord provides mechanical design solutions using platforms such as AutoCAD and Solid Works. The design of test fixtures is based on Customer Requirements such as a multi DUT testing for End-Of-Line production testing or a Single DUT test fixture for performance/validation purposes.
Accord also has expertise in designing robust Break-in Break-out Boxes which can split multiple signals to several connectors. This is highly essential in designing multi-DUT test systems. In Accord's design, minimal wiring is ensured with neat routing to reduce wear and tear as well as easy Maintenance.
For RF testing, Accord has designed RF shield boxes that ensure higher isolation from external components to test the DUT in non-signaling mode.
For single DUT testing, flexibility for connection and disconnection along with durability is a very important aspect and Accord uses an imperishable ITA (Interface Test Adapter) solution.
ATE Software Development
Accord's Engineers are experienced in developing ATE software using various tools like NI’s LabVIEW, TestStand, LabWindows/CVI and Python.
Accord provides a Layered Software Architecture as it simplifies managing the software. Additionally, it is also cost effective approach and saves development time.
Accord constantly strives to address the Customer’s challenges like parallel testing, test time optimization, reliable results, and test evolution. In addition, for keeping a track record of DUTs, Accord supplements Database Management Solutions on local as well as remote servers using popular databases like MySQL.
Accord also provides Test Engineering Services to cater to enhancement of legacy Test Systems.
Accord delivers all aspects of the ATE design to the Customers in the form of a detailed Requirements, Design and Validation Documents along with the developed Source code. Release notes and Validation Reports of the ATE accompany each release of the Test System. Accord recognizes that documentation is a very important aspect of Test System Development Lifecycle and hence provides utmost attention in capturing every single detail in the documentation.
