Power Supply ATE Workflow
If you’ve spent any time managing Automated Test Equipment (ATE), you’re likely familiar with the frustrations that come with proprietary programming tools. Often, they lack user-friendly interfaces or robust file management features, making even routine tasks, like upgrading or swapping a Digital Multimeter (DMM), more complicated than necessary. That’s where Autotest’s APG software comes in. It was specifically designed to simplify and streamline ATE programming, offering versatility and ease of use that sets it apart from other tools in the market.

Why Use APG?
Autotest’s APG stands out for its ability to work seamlessly with a broad range of testing devices, from AC/DC sources to oscilloscopes, digital multimeters (DMMs), and more. Whether you’re looking to upgrade an existing tester, integrate new hardware, or expand your testing capabilities, APG makes the process remarkably straightforward.
For instance, consider what happens when you need to replace a source that’s been in use for over a decade. Normally, this would require substantial rewiring, reprogramming, or at the very least, adjustments to your test programs. But with APG, you can introduce the new model while keeping your original test programs almost intact. The software’s commands, such as “Set Line Voltage,” are standardized, so they remain consistent across different device models and generations.
This means you can keep pace with new technology while preserving your existing test programs, even ones developed over 10 years ago. The updates required for integrating new devices are typically compact—often less than 5 MB—and the software architecture ensures minimal changes are needed for your test programs or user functions. This makes APG ideal for any testing environment that needs to remain flexible and responsive to equipment upgrades.
A Streamlined Approach to Test Programming
One of the key benefits of APG is its ability to make test programming as simple as possible. The Integrated Development Environment (IDE) features a user-friendly interface that’s intuitive, even for engineers who may not have extensive coding experience. APG’s modular command structure allows you to focus on the testing itself rather than on writing long strings of code.
For example, turning on a DC supply and reading a Unit Under Test (UUT) output only takes three lines of code in APG. This streamlined approach reduces development time and lowers the likelihood of coding errors, which can be a critical factor in environments where time and accuracy are essential.
Because APG is designed to work with a wide variety of testing devices, it ships with comprehensive libraries of pre-built user functions. These modular commands can be adapted for your specific equipment, and if you need something more tailored, APG allows you to create custom functions with ease. This not only enhances the flexibility of the software but also improves the overall manageability of your testing code.
Troubleshooting Made Easy with DART
When something goes wrong in a testing setup, finding and resolving the issue quickly is crucial. APG’s Design and Repair Testing (DART) tool makes troubleshooting more efficient by giving you real-time visibility into the state of your test equipment. With DART, you can see live data on instrument settings, ranges, and modes while the test is running. You can also make manual adjustments on the fly, which is invaluable for troubleshooting specific issues.
For instance, say you’re running a line regulation test, and a unit passes at a high voltage level but fails at the lower range. DART lets you pinpoint the issue—likely located in the low-level input voltage circuitry—so you can address it directly. By isolating the problem area quickly, APG reduces the time it takes to diagnose and repair faulty units, making your testing process more efficient overall.
Environmental Testing and Beyond
If your work involves environmental testing, where precise control of conditions like temperature and humidity is critical, APG has you covered. The software integrates seamlessly with environmental chamber control systems, allowing you to create and execute automated test sequences that take environmental variables into account. This means you can simulate different environmental conditions with accuracy, log the results, and ensure your tests meet exacting specifications.
For example, if you’re testing how a unit responds to extreme temperature fluctuations, APG allows you to set and monitor those conditions while collecting detailed data throughout the process. This is particularly useful in industries like aerospace or green energy, where environmental stresses play a significant role in product reliability.
APG’s adaptability also extends to non-standard testing scenarios, making it a highly flexible tool for a variety of applications. Whether you’re working with environmental chambers, conducting multi-step tests, or logging extensive datasets, APG allows you to customize your test processes to meet your specific requirements.
Supporting Repair Depots and Field Maintenance
Repair depots, especially those dealing with malfunctioning Units Under Test (UUTs), can benefit significantly from APG’s capabilities. The software’s debugging features help you isolate problems quickly, minimizing downtime for your equipment.
For instance, let’s say a power supply unit fails a test. APG enables you to run the program up to the point of failure and then begin the debugging process from there, instead of starting from scratch. By focusing only on the problem areas, you can reduce repair time, enhance diagnostic accuracy, and get the equipment back online faster.
APG’s Long-Term Compatibility
One of the standout features of APG is its long-term compatibility. It’s fully compatible with Autotest’s legacy hardware, including the A100 chassis and boards, as well as newer systems. This backward compatibility means that even if your equipment has been in use for over two decades, you can still integrate APG without needing to overhaul your entire setup.
APG also works seamlessly with modern operating systems, including Windows 11, ensuring that your testing environment stays up-to-date with the latest software developments. This forward-looking design means you won’t have to worry about obsolescence or costly hardware replacements any time soon.
Industry Applications
APG has been successfully implemented across various industries, including military aerospace, green energy, commercial production, and medical devices. In each of these fields, precise testing is critical, and APG rises to the challenge.
- Military Aerospace: APG ensures precision in power supply testing, adapting to the rigorous standards required for mission-critical equipment.
- Green Energy: As renewable energy technologies evolve, APG provides the flexibility needed to test new power systems, ensuring reliability and efficiency.
- Commercial Production: APG reduces time-to-market for electronics, streamlining the testing process and maintaining consistency across different product lines.
- Medical Devices: In an industry where reliability is essential, APG ensures accuracy in life-critical equipment testing while complying with strict regulatory requirements.
Future-Proof Your Power Supply Testing Processes
As technology continues to evolve, so too does APG. Future developments include cloud connectivity for enhanced data sharing and remote collaboration, as well as expanded device support for emerging technologies. Whether you’re testing RF systems, power electronics, or the latest renewable energy solutions, APG will continue to adapt alongside you. By integrating APG into your testing setup, you’re not just investing in a current solution—you’re future-proofing your operations. With its minimal coding requirements, real-time debugging, and long-term compatibility, APG is designed to meet both your immediate and future needs, making it the ideal choice for test engineers and program managers looking for efficiency, adaptability, and reliability in their testing environments.
