Draw Your Own Solution

With LabVIEW, you build graphical programs called virtual instruments (VIs) instead of writing text-based programs. You quickly create front panel user interfaces that give you the interactive control of your system. To add functionality to the user interface, you intuitively assemble block diagrams- a natural design notation for engineers and scientists.

Create the Front Panel

On the front panel of your VI, you place the controls and data displays for your system by selecting ob jects from the Controls palette, such as numeric displays, meters, gauges, thermometers, LEDs, charts,and graphs.When you complete and run your VI,you use the front panel to control your system whether you move a slide, zoom in on a graph, or enter a value with the keyboard.

Construct the Graphical Block Diagram

To program the VI, you construct the block diagram without worrying about the syntactical details of text-based programming languages. You do this by selecting objects (icons) from the Functions palette and connecting them together with wires to transfer data among block diagram objects. These objects include simple arithmetic functions, advanced acquisition and analysis routines, network and file I/O operations, and more.

Dataflow Programming

LabVIEW uses a patented dataflow programming model that frees you from the linear architecture of text-based programming languages. Because the execution order in LabVIEW is determined by the flow of data between nodes,and not by sequential lines of text,you can create block diagrams that execute multiple operations in parallel. Consequently, LabVIEW is a multitasking system capable of

running multiple execution threads and multiple VIs in parallel.

Modularity and Hierarchy

LabVIEW VIs are modular in design, so any VI can run by itself or as part of another VI. You can even create icons for your own VIs, so you can design a hierarchy of VIs that serve as application building blocks. You can modify, interchange, and combine them with other VIs to meet your changing application needs.

Graphical Compiler

In many applications, execution speed is critical. LabVIEW is the only graphical programming system with a compiler that generates optimized code with execution speeds comparable to compiled C programs. You can even use the LabVIEW profiler to analyse and optimize time-critical operations. Consequently, you increase your productivity with graphical programming without sacrificing execution speed.

Measurements and Mathematics

LabVIEW includes a variety of other measurement analysis tools. Examples include curve fitting, signal generation, peak detection, and probability and statistics. Measurement analysis functions can determine signal characteristics such as DC/RMS levels, total harmonic distortion (THD),impulse response, frequency response, and cross-power spectrum. LabVIEW users can also deploy numerical tools for solving differential equations, optimization, root finding, and other mathematical problems.In addition, you can extend these built-in capabilities by entering MATLAB or HIQ scripts directly in your LabVIEW programs. For charting and graphing, you can rely on the built-in LabVIEW 2D and 3D visualization tools. 2D tools include features such as autoscaling X and Y ranges, reconfigurable attributes (point/line styles, colors, and more)and cursors, Microsoft Windows users

can employ OpenGL-based 3D graphs and then dynamically rotate, zoom, and pan these graphs with the mouse.

Development System

The LabVIEW Professional Development System facilitates the development of high-end, sophisticated instrumentation systems for developers working in teams, users developing large suites of VIs, or programmers needing to adhere to stringent quality standards.Built on the Full Development System, the Professional Development System also includes the LabVIEW Application Builder for building stand-alone executables and shared libraries (DLLs）and creating distribution kits. In addition, the development system furnishes source code control tools and offers utilities for quantitatively measuring the complexity of your applications. With graphical differencing, you can quickly identify both cosmetic and functional differences between two LabVIEW applications.We include programming standards and style guides that provide direction for consistent LabVIEW programming methodology. The system also contains quality standards documents that discuss the steps LabVIEW users must follow to meet internal regulations or FDA approval. The Professional Development System operates on Windows 2000/NT/Me/9x,Mac OS, HP-UX, and Linux.

LabVIEW Full Development System

The LabVIEW Full Development System equips you with all of the tools you need to develop instrumentation systems. It includes GPIB, VISA, VXI, RS-232, DAQ, and instrument driver libraries for data acquisition and instrument control. The measurement analysis add DC/RMS measurements, single tone analysis, harmonic distortion analysis, SINAD analysis, limit testing, signal generation capabilities, signal processing, digital filtering, windowing, curve fitting, statistics, and a myriad of linear algebra and mathematical functions. The development system also provides

functions for direct access to DLLs, ActiveX, and other external code. Other features of the system include Web publishing tools, advanced report generation tools, the ability to call MATLAB and HiQ scripts, 3D surface, line, and contour graphs, and custom graphics and animation. The Full Development System operates on Windows 2000/NT/Me/9x, Mac OS, HP-UX, and Linux.

LabVIEW Base Package

Use the LabVIEW Base Package, the minimum LabVIEW configuration, for developing data acquisition and analysis, instrument control, and basic data presentation. The Base Package operates on Windows 2000/NT/Me/9x.

Debug License for LabVIEW

If you deploy LabVIEW applications, including LabVIEW tests for use with Test Stand, the debug license allows you to install the LabVIEW development system on the target machines so you can step into your test code for complete test debugging. This license is not intended for program development.
