Why Choose NI For PMUs And Wide Area Monitoring


PMUs have helped foster high speed data gathering from the grid with some utilities capturing phasor data as fast as 1 sample per cycle. As adoption and experience with PMU data grows, new possibilities emerge to help better monitor and control the dynamic health of a utility grid. PMUs built on NI technology have several advantageous features that can help utilities, power systems engineers, a... » read more

Best Practices For Saving Measurement Data


You collect data to make decisions. However, an inefficient file format may cause problems when analyzing your data. The key to choosing a file format for your application involves thinking about the current system requirements and how the file can adapt for future application needs. To help you organize your file format for your application, use the guide and checklist of questions: • Ho... » read more

Own Test Architecture To Meet Ever-Growing Test Coverage


Automotive consumers worldwide are increasingly basing their purchase decisions on the vehicle’s user interface, or human-machine interface (HMI). An in-vehicle infotainment (IVI) or car multimedia system, together with a digital cockpit, heavily influences how drivers and passengers feel about vehicles. And while HMI-related automotive electronics account for 70 percent of all in-car code, e... » read more

The Basics of Amplitude Modulation


Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, it is far more efficient to send data by modulating it onto a higher frequency "carrier wave." Higher frequency waves require smaller antennas, use the available bandwidth more efficiently, and are ... » read more

Design of Phased-Array Antennas for MIMO & Beam-Steering Applications


This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems. It examines the new capabilities recently added to the NI AWR Design Environment platform for developing the RF front-end hardware supporting these new antenna systems, which must be optimized for performance, reliability, compactness, and cost.

Using a Fault Insertion and Current Sensing Unit


When testing embedded software on mission critical electronic control units, like those used in automobiles or aircraft, it is important to validate the behavior with external faults for example if the integrity of the signals to the controller are compromised. The SLSC-12251/2 products from NI are designed for this purpose, these modules can be inserted into the signal path between the data ac... » read more

Peak Signal-To-Noise Ratio As An Image Quality Metric


The term peak signal-to-noise ratio (PSNR) is an expression for the ratio between the maximum possible value (power) of a signal and the power of distorting noise that affects the quality of its representation. Because many signals have a very wide dynamic range, (ratio between the largest and smallest possible values of a changeable quantity) the PSNR is usually expressed in terms of the logar... » read more

Design, System Integration and Testing of Radar Systems


This article discusses some of the fundamental research and development challenges in both the digital and RF/millimeter wave domains (such as waveform generation, receiver algorithms and transmit/receive front ends) and addresses current and future directions in design, system integration and test. Radar applications are becoming more diverse and commercialization is accelerating due to sig... » read more

What is STS Software Bundle?


The STS Software Bundle provides all the software tools and hardware drivers you need to efficiently develop and deploy test programs, interactively debug, and maintain and calibrate the NI Semiconductor Test System (STS). NI will release new bundles regularly to incorporate new functionality and hardware drivers. The STS Software Bundle includes tools for interactive measurements and debugg... » read more

Solutions For Engineering Curricula


Topics in engineering courses vary widely from elementary to the sophisticated and integrating project-based learning into each can be a monumental undertaking involving months of research, emails, and meetings. Simplify your proposal by preparing with National Instrument's recommended solutions for each class, comparing the benefits of each recommendation to make a fully informed decision. ... » read more
