Selecting an Approach to Build Flexible, Cost-Effective ECU Production Test Systems


Electronic control units (ECUs) were invented in the 1970s. At that time, people needed to improve fuel economy due to the oil crisis, which meant finding a way to make engines run cleaner and pollute less. Engines used a mechanical device called a distributor to control spark timing and a carburetor to control the fuel mixture. This mechanical system had minimal tuning and adjustment capabilit... » read more

Advanced Features Of High-Speed Digital I/O Devices: Data Delay


In high speed digital communications, because of factors such as setup time and hold time, it might be important to delay the data from the edge of the clock. The different settings and parameters that affect data delay are discussed in this white paper. To read more, click here. » read more

Under The Hood Of NI Linux Real-Time


The NI LabVIEW Real-Time Module supports the NI Linux Real-Time OS, available on select NI hardware. In this article, learn about specific new features and advanced topics to get the most out of NI Linux Real-Time for your application. To read more, click here. » read more

Advanced Features Of High-Speed Digital I/O devices: Hardware Compare


This paper describes how to use Hardware compare on the NI-HSDIO devices. The hardware compare feature allows users to perform digital comparisons of data on device itself. This allows for real time hardware comparison, which is not possible if data is transferred back to the host computer. This allows for tests such as Bit Error Rate Testing (BERT) and digital waveform comparisons. To read ... » read more

Advanced Features Of High Speed Digital I/O Devices: Double Data Rate


As clock speeds and data rates continue to increase, designers of digital integrated circuits are creating new ways to maximize the rate of data being sent into and out of digital devices. One such method is known as double data rate (DDR). With single data rate (SDR) devices, data is latched on either the rising or falling edges of the sample clock. A DDR device latches data on both the rising... » read more

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
