Rethinking the DIY Approach to Automated Test Equipment Design
By Jeff Elliott I
n an industrial setting, developing Automated Test Equipment (ATE) in- house is often approached as a DIY (do-it-
yourself) project involving the ambitious task of constructing a critical support system using internal engineering resources. ATE systems serve the critical purpose
of ensuring that electronic devices operate according to specifications in the field. The aerospace and defense sectors make substan- tial investments in ATE due to the criti- cality of lifesaving electronics utilized in military equipment such as aircraft, naval vessels, and ground vehicles, as well as in various systems like weapons, radar, and wireless communication. Automated Test Systems (ATS) are
widely utilized for testing automotive electronics, batteries, and electronic drive systems in the EV market. ATEs are also used to optimize the performance of tele- com infrastructure, analyze and improve the efficiency of renewable energy sys- tems, and validate consumer electronics. However, a common misconception is
that designing and building ATE systems is a straightforward process, one that merely requires identifying test require-

ments and assembling the necessary compo- nents. In reality, effective test system devel- opment demands expertise in test system architecture, component selection, software integration, and regulatory compliance, mak- ing in-house development a significant chal- lenge for most organizations. While some enterprises attempt to
develop ATE systems in-house, the complex- ity and cost often outweigh the benefits,
diverting focus from core technological advancements. For some companies there can be advantages to turning to specialized providers that can provide all, or parts, of ATE systems.
Advantages of Outsourcing “Many companies are reevaluating in-
house design strategies and choosing to out- source all or significant portions of their auto- mated test systems to specialized providers,” says Andrew Engler of Intepro
