Automated Test Equipment | Its Components, Purpose to Use, And Benefits

The global market for automotive test equipment (ATE) is worth $6 billion as of 2019. We expect this number to go up as more and more equipment is made with electronics whose functionality and performance must be confirmed and tested before they can be used or sold.

Automated test equipment is a useful data diagnostic and acquisition tool that can test a wide range of electronics in industries like aerospace and defense, industrial automation, and automotive, among others.

ATE is directly in charge of ensuring that the end users of electronic equipment get devices that work as intended and don’t put them in danger.

Learn About Automated Test Equipment 

Automated test equipment (ATE), also called “automated testing equipment,” is computerized machinery that uses test instruments to test the functionality, quality, performance, and stress of electronic systems and devices and then evaluates the results. As its name suggests, ATE automates electronic test equipment and processes that were once done by hand, requiring very little interaction from a person.

The same thing can also be called automated or automated testing equipment. Both of them use the same ATE abbreviation. They are just different names for the same piece of gear.

Components of Automated Test Equipment

The main parts of typical automated test equipment are software, hardware, signal sources, test instruments, and test probes or handlers.

1. Hardware:

Hardware, such as standard 19-inch rack mount workstations and servers, power supplies, PXI modules and PCIe backplanes, embedded controllers, interface modules, analog inputs and outputs, AC/DC outlets, digital input/output 

2. Software:

It is used for making tests and managing data storage, collection, analysis, and reporting.

3. Test Instruments:

Instruments for testing, like a digital storage oscilloscope (DSO), a digital multimeter, and a capacitance, inductance, and resistance (LCR) meter, are used to find problems.

4. Signal Sources:

Signal sources include an arbitrary waveform generator (AWG), a function generator, a pulse generator, or a radio frequency (RF) generator.

5. Test Probes And Handlers:

Test probes or handlers connect a UUT, DUT, or EUT to a test instrument.

Purpose of Automated Test Equipment

The main goal of ATE systems is to make sure that electronic devices work how they are supposed to once they are in the hands of the customer. This keeps bad or broken devices from getting on the market.

If problems or flaws are found during testing, ATE also helps figure out why. This lets manufacturers fine-tune and fix their devices as needed before sending them to customers.

ATE systems also cut down on testing time and save companies a lot of money by digitizing and automating procedures, equipment, and processes that used to be done by hand.

Benefits of Automated Test Equipment

1. Reduced Cycle And Test Times:

Test and cycle times are shorter because automation removes the need for engineers to troubleshoot, which can take a wide range of time.

2. Reduction of Data Input Errors:

Errors made when entering data need to be cut down on or stopped. Automated test equipment always gets it right as long as there are no problems with the equipment.

3. Cost-Effective Use of Engineering Resources:

More efficient and cost-effective use of engineering resources: engineers can focus on testing problems that come up instead of doing tests by hand.

4. Accurate Test:

Manual testing depends on the speed and skills of the test engineer, so the speed and quality of the results depend on the test engineer and their skill set.

Major aerospace and defense companies all over the world use Automated test equipments. However, ATE helps any industry that needs reliable, durable, and cyber-secure ATE computers.
