Depending on the product, the machines that we are referring to could mean a combination of Automatic Test Equipment (ATE), handler, interface board, and test program that drives the ATE, as with the case of the IC chip testing. Test automation is a big part of a test engineer's job. The whole intention of automating the test is as follows:
Automatic test equipment diagnostics is the part of an ATE test that determines the faulty components. ATE tests perform two basic functions. The first is to test whether or not the Device Under Test is working correctly. The second is when the DUT is not working correctly, to diagnose the reason.
Creates constant-amplitude variable frequency sine waves to test frequency response Transistor tester: Tests transistors Tube tester: Tests vacuum tubes (triode, tetrode etc.) Wattmeter: Measures power in a circuit Vectorscope: Displays the phase of the colors in color TV Video signal generator: Generates video signal for testing purposes Voltmeter
Automatic test equipment, any apparatus that performs tests using automation; Built-in test equipment, passive fault management and diagnosis equipment built into airborne systems to support maintenance; On-board diagnostics, test equipment for automobiles; Transistor tester, used to test the electrical behavior of transistors and solid-state ...
Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.
Automation engineers are responsible for creating detailed design specifications and other documents, developing automation based on specific requirements for the process involved, and conforming to international standards like IEC-61508, local standards, and other process specific guidelines and specifications, simulate, test and commission ...
Another test automation practice [2] is continuous integration, which explicitly supposes automated test suites as a final stage upon building, deployment and distributing new versions of software. Based on acceptance of test results, a build is declared either as qualified for further testing or rejected. [ 3 ]
The common understanding of DFT in the context of Electronic Design Automation (EDA) for modern microelectronics is shaped to a large extent by the capabilities of commercial DFT software tools as well as by the expertise and experience of a professional community of DFT engineers researching, developing, and using such tools. Much of the ...
