HOW TO BUILDA BETTERTEST STATION
DESIGN FOR TODAY AND TOMORROW1.
With products and technologies changing so quickly, it’s never been so important to have flexible and scalable test equipment. The more you can test with it over the long term, the better the investment. So when designing a test station, think of how your product testing might evolve. Will you need
di�erent instruments, more automation or quicker access to the electrical panel? The key is a solid yet flexible framework.

ALL PURPOSE Start by identifying which hardware and so�ware components you need for all your testing versus what you will need for each product. For example:
And don’t forget to allow 30-35% extra capacity for:• Rack space/instrument slots• Communication ports• Switching channels, etc.

5 Best Practices for a Scalable and Flexible Solution / Averna
Military and aerospace organizations excel at getting the most out of their test instruments. They typically choose modular, flexible ones like PXI that will cover multiple purposes to ensure long-term use and value.
So when you’re designing your test station, ask questions like “Will this let us test multiple products?” and “Will it be easy to upgrade?” This will help you avoid buying an instrument that you might not need next year.

IDLE
Many OEMs typically go through cycles where one product requires intense testing but only several months a year or several days per week, meaning that expensive test equipment can be idle for signi�cant periods.
To keep your station working, consider moving any intensive testing requirements into swappable �xtures and/or so�ware packages. That way you can quickly adapt the station for testing other products.

Solve more of your test issues with swappable, intelligent �xtures rather than with expensive instruments, and put elements that you will only need for one product in your �xtures. For example:
• JTAG programmer• Drivers• UUT switching
Then put a solid switch controller in the station with all control lines routed to the �xture – to avoid having to over-specify switching subsystems.

Connecting �xtures directly to your instruments is time-consuming and prone to wear and tear. Instead, use an interchangeable test adapter. While a rugged ITA can be pricey, it will pay for itself in the long run.
For example, it protects your expensive instruments by creating a robust interface between them and your �xtures, while enabling you to quickly convert the station over to begin testing another product.

SAY “NO” TO CUSTOM SOFTWARE4.
Developers come and go but your test infrastructure is there for the long term. Employ a test executive like NI TestStand because it easily handles:
• Multiple products• All inbound/outbound data• Test updates
And it will make it simple to integrate test-data management so�ware for the consolidation of test results and reporting purposes.

Working with just one test executive so�ware tool will ensure that your test stations can be easily updated and used by more personnel. The last thing you want is cryptic code and custom interfaces slowing down your testing.
A standard test executive also greatly reduces business risk. If your so�ware architect leaves the company, for example, it will be much easier to �nd someone to quickly take over test updates and troubleshooting.
CUSTOM TEST ARCHITECTURE IS RISKY BUSINESS.

Let’s face it – building a new test station is a signi�cant investment. That’s why it’s crucial to evaluate the bene�ts and return on investment, such as:
• Fewer expensive, one-purpose instruments• Smarter, swappable �xtures• Increased station flexibility/use• Less time needed for test updates

Finally, with a standardized and flexible approach to building a new test station, multiple departments and partners like these will �nd it easier to collaborate on testing:
• R&D• Engineering• Manufacturing• Repair centers
And you will also boost product intelligence, cover evolving feature sets and improve business results.
