An Ultimate Guide | Automated Test Equipment Advantages And Its Components

Data acquisition and diagnostic tools such as Automated Test Equipment (ATE) are useful in the testing of a wide range of electronics in various industries, including defense and aerospace as well as automobiles and industrial automation. In addition to ensuring that electronic devices work as intended, ATE also ensures that end users are not put in harm in any way during their use.

Now wondering what exactly is automated Test Equipment? And what are its components? 

Let’s begin without further ado.

Automated Test Equipment System Consists of Following Parts

Hardware, software, test instruments, signal sources, and test probes or handlers are all part of a typical automated test solution.

• PCIe backplanes and related PXI modules; interface modules; embedded controllers; analog input and output; digital input and output; and AC/DC outlets, all of which can be mounted in a standard 19-inch rack.
• Data collection, storage, reporting, and analysis software for test development and management
• Digital oscilloscopes, digital multimeters, and inductance, capacitance, and resistance (LCR) meters are examples of test instruments.
• An AWG, a function generator, a pulse generator, or an RF generator are examples of signal sources.
• Test probes or handlers, connect a test instrument to a DUT, UUT, or EUT and establish a connection.
• Consolidated test towers, which resemble data center server rack cabinets, typically house all of these components. The size and portability of these test towers can range widely, from small, mobile units to mammoth, stationary ones.

Keep in mind – Not all automated test solutions use the same hardware and software as well as test instruments and signal sources; these configurations can vary widely depending on the type of device being tested and the parameters that need to be measured.

What Is The Purpose of ATE?

Automated Test Equipment utilizes a wide range of test instruments and signal sources to control, monitor, collect data, and derive insights, including

• Digital multimeters, which can measure voltage, current, and resistance.
• Inductance, capacitance, and resistance (LCR) meters are used to measure these properties.
• Display and analysis of signal amplitude, distortion, and other characteristics using digital storage oscilloscopes (DSOs).
• RF or vector signal generators (VSGs) for the generation of RF signals.
• Waveform generators (AWGs) allow users to create their own electrical waves.

What Are The Advantages of ATE?

Testing and evaluation systems are used by manufacturers and distributors of electronic devices in order to make sure that they work and perform as expected once they reach consumers, preventing defective products from entering the market.

In the event that faults or defects are discovered during testing, ATE can assist in determining the root cause, allowing manufacturers to make necessary adjustments before shipping their products to customers. Additionally, by digitizing and automating traditionally manual testing equipment and procedures, ATE systems help companies save a great deal of money and time.

As it turns out, there are some major advantages to using ATE, including:

Time Savings: the automation factor ensures consistent test and cycle time consistency by eliminating widely variable troubleshooting by engineers, thus reducing time spent on testing and cycle.

Error Proof: Manual testing relies on the speed and skills of the test engineer, so the results are only as fast and accurate as the test engineer and his or her skillset. Whereas having ATE can reduced the stress  and time. Also, error reduction or prevention provided the equipment is working properly, ATE always gets the job done correctly.  

Cost Effective: Engineers can focus on testing issues that arise instead of manually performing tests, which allows them to use engineering resources more efficiently and cost-effectively.
