ATE / 31 What is LabWindows/CVI? The proven LabWindows/CVI environment features code generation tools and prototyping utilities for fast and easy C code development. It offers a unique, interactive ANSI C approach that delivers access to the full power of C with the ease of use of Visual Basic. Because LabWindows/CVI is a programming environment for developing measurement applications, it includes a large set of run-time libraries for instrument control, data acquisition, analysis, and user interface. LabWindows/CVI also contains many features that make developing measurement applications much easier than developing in traditional C environments.

ATE / 31 Is VXI dead? VXI continues to get investment for applications that require the high-speed and high-density benefits this architecture delivers. Weve found VXI works well in aerospace-defense, automotive, high-speed digital, and telecom applications where tight inter-module linkages and high channel count are critical. But as noted above, this capability comes at a steep price premium. For general-purpose instruments, and in small to medium size applications, most customers prefer to use rack & stack because they offer a manual user interface and display, they are lower cost for equivalent capability, and they offer the flexibility to use the same instrument on both the bench and in the rack.
