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

Save Time And Maximize Reuse in HIL Testing With The SLSC Extension For PXI And CompactRIO


NI SLSC (Switch, Load and Signal Conditioning) is an add-on for NI data acquisition products like PXI and CompactRIO. SLSC standardizes connectivity and provides a modular approach to signal conditioning, fault insertion and other test needs. This white paper discusses the details of SLSC and showcases the growing ecosystem of SLSC modules and accessories created by NI and NI partners. What ... » read more

Generating And Debugging Constraints For High-Speed Serial Instruments


This white paper addresses the specific need for designing constraints into your NI PXIe-6591R or PXIe-6592R High Speed Serial project. Constraints are an often overlooked requirement of the project and can take several weeks to analyze timing requirements on a design, implement constraints, and achieving successful compilations that pass timing. This guide will help reduce the amount of time s... » read more
