Automated Test Equipment’s (ATEs) are integrated systems which automate the process of testing modules, systems, devices or products. Test equipment are generally used to monitor and control the operation of a process or device, verify compliance standards, and detect and mitigate risks.

The world of R&D, Testing & Measurement is undergoing a sonic
transformation and Automated Testing is playing a key role in its
evolution. When businesses choose to invest in Automated Test
Equipment (ATE), it is often because they believe this will have a
transformative impact on their testing capabilities. ATEs enable designers
and manufacturers to optimize their test cycles for precision and reduce
the time, cost, and risk associated with testing. In this blog post, we will
explore what automated test equipment are and how it can deliver a
measurable ROI for manufacturers.

Automated Test Equipment’s (ATEs) are integrated systems which
automate the process of testing modules, systems, devices or products.
Test equipment are generally used to monitor and control the operation
of a process or device, verify compliance standards, and detect and
mitigate risks.
Test automation involves the use of software programs and operating
procedures to document, analyse, and control testing procedures so that
tests are performed consistently and in an efficient manner. During
testing, an ATE is used to control the operation of the “System under
Test (SUT)”, record and store test data, and consolidate a report on the
test’s findings. These systems can be used to test a range of products in
various industries.
The most common types of Automated Test Equipment are simulators,
evaluation systems, functional/electrical test systems, impedance test
systems, board-level testers, and networked automated test systems. In
the recent past, Users have procured a lot of ATE equipment from
Digilogic and have benefited not only with respect to having fool proof
testing but also a quicker testing process, robust test procedures which
result in a reduction in time for Govt to Market time and failures on the
field. All of this has helped our clients in reducing R&D in prototyping
without compromising on the testing methodology, finally resulting in
High profitability.

HOW DOES AUTOMATED TEST EQUIPMENT
BOLSTER YOUR ENGINEERING?
An ATE can eradicate misleading results in test reports, by automating
processes that are prone to human error. When testing is automated, test
results are consistent and cannot be misinterpreted. This can also help to
ensure consistency in the quality of products.
Additionally, ATEs can help reduce the cost of testing by reducing the
time-to-test and materials needed. This is achieved by using
programmable features on ATEs to automate testing sequences. Users
have used one Digilogic Automated test Equipment for various
applications ranging from Underwater Unit under Test (UUT) to
Ground-based high-performance UUT all the way to space-born UUT.
Every client who needs an ATE always has a unique problem at hand.
Hence, we at Digilogic need to come up with unique testing procedures
keeping in mind the client’s requirements. Unlike product bases systems,
we have to tailor-make every ATE keeping in mind our client and his
requirements.
Digilogic Automated Test Equipment are designed in a modular fashion,
enabling the user the flexibility of upgrading the system at any point in
time. The users are found to use one ATE for multiple variants of the
UUT just by plugging in additional resources to the existing setup.

KEY AUTOMATION TOOLS YOU’LL FIND IN ATE
EQUIPMENT
Computer-Controlled Systems: These systems provide an interface to
oversee the control of each module in an integrated testing system while
facilitating the exchange of information between its modules and offering
up compiled test reports after calculating the measurements from each of
the modules. The most common types of computer-controlled systems
are the digital must meter (DMU), the digital oscilloscope, the computer
terminal, waveform generators and DC power supplies.
Data Storage/Retrieval: Data storage/retrieval systems are used to record
test data into a computer-type storage device for later analysis.
Test Program Software: Test program control (or test program design
automation) systems are used to control the operation of the test
equipment by executing pre-programmed instructions. They are usually
designed to control complex ATEs and consist of a computer and
associated data input/output devices.
Signal Source: A signal source is used to provide the input voltage, current,
or frequency required to test a specific system under test.
Interface Panel: Test probes/connectors are used to interface the test
equipment with a specific system under test.

Indicators: Indicators are used to observe the operation of the system
under test manually.
DEFINE YOUR TESTING REQUIREMENTS BEFORE
SELECTING EQUIPMENT
The most important aspect of implementing an ATE effectively is to
understand the specific testing requirements of each product. This will
help you select the right equipment and design the appropriate test
fixtures. Make sure you understand the steps in testing, the required test
coverage, and the types of failures that must be detected. Once you have
this information, you can identify the type of automated test equipment
that will best support your testing requirements, including the number and
placement of fixtures on the equipment.
INTRODUCE BREAKPOINTS AND THRESHOLDS TO
TRIGGER ADDITIONAL TESTS
An advantage of Automated Test Equipment (ATEs) is the feasibility of
programming them to suit your unique testing conditions. One example
would be if the System under test is undergoing a specific test cycle, the
user shall depute one Engineer to help oversee any anomalous conditions
that may arise during testing such as Open/Short circuit conditions.
Here the Engineer would have to wait and oversee the entire test
procedure, making sure to document the conditions thoroughly. In an
ATE, the Test Program Software can be designed to automatically log

Data with specific time stamps if any thresholds are crossed or any
anomalous readings are detected. When the test cycle is completed, the
User is able to verify the test report in its entirety and come up with
actionable insights.
KEY TAKEAWAYS
Today’s manufacturing environment is more complex than ever. To meet
these challenges, manufacturers are exploring ways to streamline their
processes and drive efficiency. By utilizing automated test equipment
strategically in your manufacturing process, you can see an improvement
in production output with better financial returns. Matching the right
software and modular hardware is imperative to building successful test
systems.
At Digilogic Systems, we have been in the business to address the most
challenging automation requirements and provide our users with the best
testing platform which helps them to reduce the time to market drastically.
Our users get the unique advantage to get a custom testing platform tailor-
made to their testing needs, this helps them to cut down costs on
unwanted tests which might not be relevant to their platform. Hence
enhancing the use of the ATE design developed by us.
