Some 17 years have passed since the concept of virtual instrumentation was pioneered, changing the way engineers and scientists measure and automate the world around them. Today, virtual instrumentation is coming of age, with engineers and scientists using Virtual instruments' in hundreds of thousand of applications around the world, resulting in shorter lead times, higher-quality products, and lower costs. The building blocks of virtual instrumentation include powerfully productive software, modular measurement hardware, and commercial technologies such as the personal computer and the internet. With virtual instrumentation, engineers define the measurements in a test or control application, using intuitive software and general-purpose measurement hardware that spans a wide range of frequencies and resolutions. These tools immediately deliver the productivity, performance, and cost-saving benefits of rapidly advancing computer technologies to engineers in hundreds of industries.
