How ATE Identifies Faulty Electronic Components

Automatic Test Equipment (ATE) is used for evaluating the performance of a variety of electronic devices and software. This computer-operated machine can run a device under test (DUT) on radar units, computers, wireless routers, semiconductors, avionics and many other devices.

Simple and Complex Testing A simple ATE is comprised of a digital multimeter, which gives digital readings for basic measurements such as voltage, current and resistance. A complex ATE can be integrated with multiple applications and provides a wider selection of data for testing more complex electronic systems. These instruments are used by manufacturers, mechanics, military and other fields that rely on high performance electronic equipment.

Computer Integration An ATE device can be hooked up to a computer to store, process and display information. A computer, connected through a USB cable, is helpful in speeding up the computing of measurements for peak voltage by communicating with a Digital Signal Processing (DSP) unit in the ATE. Various parameters of an electric signal can be calculated more quickly using this type of ATE. By creating a DSP sample, for example, results of other parameters can be processed instantly.

Testing Parameters Not all devices need to be tested for all parameters, since some devices are more critical than others to function at top performance. A lifesaving medical device is an example of equipment that must be tested thoroughly with ATE, as parameters must be guaranteed.

ATE systems can be used to test multiple devices at once. Integration with additional equipment such as a high speed switching system can help accelerate tests while generating more accurate results.
