Modern Automatic Test Equipment (ATE) systems are expected to provide a platform for existing Test Program Sets (TPS), as well as enable testing of new much more advanced Units Under Test (UUT). There are many methods to provide an interface to the UUT including reusing the existing interface or the new CTI interface. Each choice made has advantages and disadvantages to the interface. One approach...
Test Program Set (TPS) runtime is one of the most important aspects in repair throughput. Considering the testing required to detect and isolate faults or failures and then verify repair during a typical maintenance event, the individual elements of a test program are usually executed at least twice. Any reduction in test execution time is therefore multiplied, increasing the importance of optimizing...
Two System Test Program Sets (TPS), Digital-Analog (DA) and Radio Frequency (RF) Calibration for the Versatile Depot Automatic Test Station (VDATS) were developed to semi-automate the process of Automated Test Equipment (ATE) calibration. Calibration for ATE in the U.S. Air Force (USAF) is defined as the verification of instrumentation accuracy by comparing the instrument to a known standard. The...
Test forensics is a systematic approach for evaluating execution results of a Unit Under Test (UUT) over a broad set of criterion. Execution results include the traditional test numbers, measured values and limits, but also include timing relationships and configuration information about the UUT and Automatic Test Equipment (ATE) used while conducting the test. Occasionally a test may pass on station...
Overcoming test-equipment obsolescence is paramount in military and aerospace applications where test systems are supporting equipment with a service life of more than 20 years. However, replacing one or more obsolete instruments in a test system can have major consequences for the deployed Test Program Set (TPS). An emulation strategy can help you incorporate new test instruments to migrate from...
The paper considers the benefits and practicalities of using the Automatic Test Markup Language (ATML) family of Standards in Test Program Set (TPS) development and life cycle maintenance. As part of any TPS development, the exchange of critical information is key to the successful development of a TPS. At a project management level, these manifest themselves at key milestones in a development projects...
