automated test equipment

The universal automated test equipment market is growing at a rapid speed. We anticipate that this figure will rise as more and more machinery is outfitted with electronics, whose performance and functioning must be examined and verified before being used or sold.

Aerospace and defense, automotive, advanced manufacturing automation, and other industries employ ATE as a handy data acquisition and scan tool for testing various devices.

In addition to guaranteeing that potential customers of electronic equipment obtain products that work and function as intended, automated test equipment is responsible for ensuring that they are not in danger.

Let’s get started right now without further ado.

What is automated test equipment?

Automatic test equipment (ATE), sometimes known as automatic testing equipment, is the computerized gear used to conduct and analyze the results of stress, performance, and quality tests on electronic devices and systems. Like the name suggests, ATE often automates manual electronic test tools and procedures while requiring little human involvement.

Equipment for automated testing is frequently referred to as automated testing equipment. They both employ the same ATE abbreviation. They just relate to the same equipment under different names.

The term “device under test” (DUT), “unit under test,” or “equipment under test” is typically used to describe the device whose characteristics the ATE evaluates (EUT).

To ensure the proper operation, functioning, and safety of individuals who will utilize or directly or indirectly receive support from such devices, ATE tests many electronic devices currently in use.

Components of automated test equipment


Hardware refers to the physical components of automated test equipment, such as the computer, monitor, cables, and probes. These components are essential for the proper functioning of the automated test equipment, as they allow for the transmission of data and the execution of tests. The hardware provides the interface for the user to interact with the automated test equipment and control the testing process.


Software refers to the computer programs and algorithms used in automated test equipment to control the testing process and analyze the results. This includes the software that runs on the computer, as well as the specialized software that is designed for specific types of tests. The software is essential for the automated test equipment to function properly, providing the instructions and algorithms necessary to carry out the tests and analyze the results.

Test instruments 

A test instrument is specialized equipment used in automated test equipment to measure or test a specific physical property or characteristic. This can include instruments such as oscilloscopes, spectrum analyzers, multimeters, and signal generators. The test instrument is essential for the automated test equipment to function properly, as it allows for the precise measurement and analysis of the physical property or characteristic being tested.

Signal sources 

Signal sources refer to the devices or generators used in automated test equipment to produce a specific signal or waveform. This can include voltage or current generators, frequency or phase generators, or noise generators. The signal source is essential for the automated test equipment to function properly, as it allows the creation of the specific signal or waveform needed for the test.

Test probes or handlers

Handlers are specialized devices or mechanisms used in automated test equipment to manipulate or position test samples or devices during testing. This can include handlers such as pick-and-place robots, test jigs or fixtures, or vacuum grippers. The handler is essential for the automated test equipment to function properly, as it allows for the precise and consistent positioning of the test samples or devices during the testing process. This ensures the accuracy and repeatability of the tests. 

These parts are typically combined into exclusive test stations, ranging in size and portability.  Likewise, tiny, mobile test stations to enormous, stationary test towers resembling the server rack cabinets seen in data centers.
