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...
During the last four decades the number of Automated Test Systems (ATS) has experienced tremendous growth at Tobyhanna Army Depot (TYAD). This is characterized in the proliferation through Base Realignment and Closure acquisition and in-house development of a wide variety of general and special purpose ATS - to date there are 94 unique ATS and a total of 230 ATS. With advancing technology and increasingly...
With virtual instrumentation and graphical system design, the application requirements ultimately dictate the shape and form of the structural test and monitoring system. Virtual instrumentation offers more complete, more capable, and lower cost structural test and monitoring systems. This paper will provide an architectural view of modern structural test and monitoring systems, diving into both COTS...
Analysis of digitized waveforms requires an understanding of the limitations of the acquisition hardware, an understanding of how digital sampling interacts with the waveform shape, and an understanding of how the desired measurements are influenced by the sampling operation. By paying attention to these considerations and following some general guidelines an acquisition system can be tuned to get...
This work presents a power electronics health monitoring test platform for assessing modern power drives and electric machines with regeneration capabilities. This versatile platform combines data acquisition of critical system signals that are used for analysis as health indicators for the overall system and individual components such as power semiconductor devices. The test platform combines hardware...
