Advanced Topics in LabWindows/CVI

Shahid F. Khalid has over 30 years of experience in software engineering. At Boeing he is presently working on the design and implementation of the Next Generation Automatic Test Equipment using LabWindows/CVI. In the past he has used LabWindows/CVI to test embedded software for the engine control unit on Delta IV rockets, to create applications for laser beam alignment, and to control and diagnose automatic test equipment. He is the author of LabWindows/CVI Programming for Beginners (0-13-016512-3), also published by Pearson PTR.
