PyLab_Works is a visual design package, much easier to learn and to extend than LabView. PyLab_Works also supports a MatLab-like environment for doing scientific and engineering calculations but with a much better general programming environment (thanks to Python + Scipy) than MatLab. Even kids can use it! New in v0.4 ADC-Brick supports USB-6008, USB-6009, SoundCard Circuit Plots, draws all kind of responses of an (electrical network) FIR Filter design Brick PyCircuit integration Auto Brick generation, tested on Numpy, Scipy and PIL ShowCase Homepage ( chapter: PyLab Works ) New flash demo: Integration of VPython, 10 minutes, 20 MB The current status is alfa, although we use large parts of it as a regular tool in our daily work (replacing MatLab and LabView).

Virtual Instrumentation and Traditional Instruments

What is a virtual instrument and how is it different from a traditional instrument? Virtual instruments are defined by the user while traditional instruments have fixed, vendor-defined functionality. Figure 1. Traditional instruments (left) and software based virtual instruments (right) largely share the same architectural components, but radically different philosophies Every virtual instrument consists of two parts – software and hardware. By not using vendor-defined, prepackaged software and hardware, engineers and scientists get maximum user-defined flexibility.

Here are some examples of this flexibility in practice: 1. Figure 2. 2. Figure 3. Back to Top 2. An important concept of virtual instrumentation is the strategy that powers the actual virtual instrumentation software and hardware device acceleration. Fundamentally, because virtual instrumentation is software-based, if you can digitize it, you can measure it.

What Is Virtual Instrumentation? The rapid adoption of the PC in the last 20 years catalyzed a revolution in instrumentation for test, measurement, and automation. One major development resulting from the ubiquity of the PC is the concept of virtual instrumentation, which offers several benefits to engineers and scientists who require increased productivity, accuracy, and performance. A virtual instrument consists of an industry-standard computer or workstation equipped with powerful application software, cost-effective hardware such as plug-in boards, and driver software, which together perform the functions of traditional instruments.

Virtual instruments represent a fundamental shift from traditional hardware-centered instrumentation systems to software-centered systems that exploit the computing power, productivity, display, and connectivity capabilities of popular desktop computers and workstations.

About Virtual Instrumentation

What is virtual instrumentation? With virtual instrumentation, software based on user requirements defines general-purpose measurement and control hardware functionality. Virtual instrumentation combines mainstream commercial technologies, such as the PC, with flexible software and a wide variety of measurement and control hardware, so engineers and scientists can create user-defined systems that meet their exact application needs.

With virtual instrumentation, engineers and scientists reduce development time, design higher quality products, and lower their design costs. Figure 1. National Instruments introduced virtual instrumentation more than 25 years ago, changing the way engineers and scientists measure and automate the world around them. Back to Top 2. Virtual instrumentation is necessary because it delivers instrumentation with the rapid adaptability required for today’s concept, product, and process design, development, and delivery. 3. Figure 2.
