National Instruments' latest release of Measurement Studio is a set of graphical-based measurement tools that complement other text-based languages that programmers use most. Measurement Studio 6.0 includes LabView and LabWindows/CVI among others and provides developers and engineers with the tools to create a variety of integrated test, measurement, and control applications.

Measurement Studio 6.0 includes new features such as hardware integration capabilities, improved visualization and analysis tools, and Internet connectivity. Engineers can integrate vision and motion hardware into their measurement application through new task-oriented software. With this hardware compatibility, engineers can create mission critical, multifunction applications, such as an automated system that includes motion capabilities, data acquisition, and visual inspection to package and test electrical signals, check for missing parts, and scan packaging for correct labels.

Through ActiveX controls for Visual Basic and C++ Classes for Visual C++, engineers now have complete interchangeable virtual instrumentation class compatibility. LabWindows/CVI provides wizards to create and use IVI instrument drivers. With IVI drivers, engineers can interchange instrument hardware without recompiling software. LabWindows/CVI can incorporate ActiveX controls from other software programs or add capabilities, such as streaming video or voice control.

The new version's enhanced visualization tools allow the display of data of real-time 3-D or 2-D graphs and charts. Measurement Studio also includes a network data transfer interface called DataSocket, a high-level publish/subscribe technology that provides simplified URL addressing and low network overhead. DataSocket is the mechanism used to transfer data across networks to ActiveX controls for real-time viewing.

Measurement Studio also has tools for an array of advanced functions for signal analysis. Engineers can compute statistics, discover the decay rate of a particular signal through curve fitting, and dissect frequency signals with frequency and time domain analysis routines. By conducting frequency analysis, engineers can pinpoint a particular part of a machine that is failing, calculate the RPMs of an internal object, or determine the exact tone of a test signal.
