1. Smart Devices
For many of us, the Internet of Things (IoT) has already become a personal reality. When we control our Nest thermostat from a smartphone, measure the number of steps we’ve taken with a wristband, or stream video to a tablet, we enjoy the benefits of a device that can sense, connect, and compute. However, even for early technology adopters, the IoT is still in its infancy. Gartner estimates there will soon be more connected devices than humans, and by 2022 each household could contain more than 500 connected devices.
2. Outsmarting Your Smart Device-Under-Test (DUT)
What makes a test system smart? It takes flexible and software-defined I/O modules to sense the right connectivity for synchronization and data streaming (whether locally or to the cloud), and computational horsepower for signal processing where it can have the most benefit.
NI’s approach to automated test empowers smarter test systems. With a platform built from the ground up for customization—either through the latest commercial technology or through your domain knowledge—you become part of a living, breathing, and evolving ecosystem that’s already responsible for creating innovative approaches to automated test across every industry. No other technology company in test and measurement spends more on R&D to upgrade the intelligence of your test system. No other vendor has the track record of growth and commitment to collaborating with our customers. And we’re only getting started.
Read on to learn how you can build smarter test systems to tackle smart devices with help from an open platform combined with a vibrant ecosystem.
3. A Platform Built for Customization
All technology vendors talk about platforms. With large engineering teams, a sense of hierarchy and modularity is crucial for efficient development. To forgo a platform-based approach is to doom yourself to re-engineering, often from the ground up, whenever your system reaches a breaking point. In past eras, you may have been able to prolong the inevitable for years or even decades, but the pace of smart device innovation is making the unexpected routine.
So all test and measurement vendors use platforms of one form or another to deliver their product capability to users. But that doesn’t make all platforms equal. Some are purely for the purpose of internal design efficiency. If an oscilloscope vendor can use the same computing circuit daughterboard on every scope, they are using a common platform for one part of the design while the sample rate, bandwidth, or screen size of their scope evolve. The customer doesn’t see or interact with the computing “platform,” but it helps the vendor release new scopes faster, and there’s value in that.

At NI, we take a radically different approach to platforms. We create them to help make our users more productive—sometimes even at the cost of our own efficiency. We expose APIs for our software and common mechanical/electrical interfaces for our hardware so pieces can be interconnected in whatever combination works best for the user. To follow the computing “platform” analogy for a scope, we give you the ability to specify what type of computing power you need for your scope and upgrade it over time, if needed, to keep pace with your processing requirements. While other vendors make you buy a whole new scope, NI gives you the ability to optimize the modular pieces of your instrumentation.
More and more capability of hardware is being moved to the software domain. To keep pace with the innovation of your smart device, you need extreme flexibility in the software or your instrumentation and test system. Take, for example, new digital predistortion techniques in RF amplifier technology. To effectively model and test those algorithms, your instrumentation needs to be open and modifiable through easy-to-understand software. The intellectual property that makes the instrument successfully test a power amplifier may have nothing to do with the instrument—but it clearly needs to work optimally with the instrument. A platform-based approach built for customization makes that not only possible but also easily done with the right domain expertise on the smart device.
4. An Ecosystem Built on the Platform
Once you accept that a user-customizable platform is necessary to keep pace with smart devices, you might then start to worry about your own ability to customize it. By contrast, box instruments have been providing, for decades, push-button answers to common measurements and firmware-based algorithms that offered confidence in the validity and traceability of the measurement. How can that same level of confidence and trust be imparted from something you customized? In summary: an ecosystem of customization IP.
The same could be said about the iPhone. The promise of the App Store isn’t very appealing if you have to write all the apps yourself. But when a truly open platform is created, along with the clearly defined APIs and hardware specifications, an ecosystem often develops. That’s what created the iPhone into the multibillion app download machine it’s become, and it’s what makes NI automated test capability the most trusted approach for lowering the cost of test.
handling the intricacies of test system development on an open platform.
The NI ecosystem is made up of many parts:
- User Community—There are hundreds of thousands of active users of NI software, composed of LabVIEW, TestStand, and LabWindows™/CVI. That doesn’t include the number of developers working with NI hardware drivers. In many ways, they are facing the same challenges with smart devices as you are, and they actively share their experiences in our online and in-person user communities. If you work at a large multinational organization, there’s a good chance a LabVIEW user group already exists at your company. If you represent the entire test department at your small business, you can benefit from online help coming from thousands of active peers. Many times, these colleagues create algorithms or example code that’s community vetted and available through the LabVIEW Tools Network. The community accomplishes an order of magnitude more (and faster) than our, your, or any other test vendor’s R&D ever could.
- Partners and Integrators—When your resources are tight or domain expertise is limited, you may need to bring in expert help. Whether it’s simple consultation or turnkey system delivery and support, the NI Alliance Partner Network has more than 1,000 partners around the world to assist. Many have deep expertise in similar automated test scenarios, and they understand from experience how to architect a smarter automated test system that can evolve over time.
- NI Support—When you need consultation with NI, our global team of more than 700 applications and systems engineers is available. With expertise in NI tools and a strong commitment to responsiveness and customer success, the NI support team can be reached by phone, email, or in-person to help you build or improve you test and measurement system to keep pace with changing requirements.
- NI Field Engineers –NI has a world-class website for information-collection and ordering test equipment. But we haven’t lost the personal connection and insight that comes from having a local field sales engineer and inside sales engineer consult with you on your purchase. You get answers and advice from engineers that have used the products, understand the catalog, and can even offer roadmap and lifecycle information in the right circumstances.
- Third-Party Hardware and Software—After the open platform descriptions are public (through APIs and supported hardware interfaces), a third-party product ecosystem can flourish. This has been true for almost 20 years with PXI, a multivendor consortium governed by the PXI Systems Alliance. The breadth of third-party software available through the LabVIEW Tools Network is also substantial, with more than three million downloads to date. In addition to finding specific IP useful to your application, the network is an opportunity for you to share and monetize the investment you’ve made in the NI ecosystem.
- NI Hardware Services—NI provides hardware services that help you achieve lowest total cost of ownership over the life of your system. NI hardware services include repair, replacement, and regional sparing, system configuration and assembly, and multiple levels of return-to-NI or on-site calibration. After shipping more than 150,000 PXI systems, the concept of calibrating and servicing modular instruments is a core competency that NI or other certified providers can perform.
As the devices you have to test become smarter, you are left with a question: Do I trust my instrument vendor to innovate fast enough for my business needs? Or perhaps more importantly, is it worth risking your business to find out?
