Data Acquisition using LabVIEW

By: Behzad Ehsani

Overview of this book

NI LabVIEW's intuitive graphical interface eliminates the steep learning curve associated with text-based languages such as C or C++. LabVIEW is a proven and powerful integrated development environment to interact with measurement and control hardware, analyze data, publish results, and distribute systems. This hands-on tutorial guide helps you harness the power of LabVIEW for data acquisition. This book begins with a quick introduction to LabVIEW, running through the fundamentals of communication and data collection. Then get to grips with the auto-code generation feature of LabVIEW using its GUI interface. You will learn how to use NI-DAQmax Data acquisition VIs, showing how LabVIEW can be used to appropriate a true physical phenomenon (such as temperature, light, and so on) and convert it to an appropriate data type that can be manipulated and analyzed with a computer. You will also learn how to create Distribution Kit for LabVIEW, acquainting yourself with various debugging techniques offered by LabVIEW to help you in situations where bugs are not letting you run your programs as intended. By the end of the book, you will have a clear idea how to build your own data acquisition system independently and much more.

GPIB


During the 1960s, long before USB, USB2, and now USB type-C dominated the bus systems on most platforms and appeared as the built-in standard on all desktop computers and laptops, a digital communication standard, originally developed by HP, was registered as an IEEE 488.x standard. This standard, also called General Purpose Interface Bus (GPIB), is still widely used and well in existence (many were sold several years back) in the test and development industry and many university labs.

We will also use an NI GPIB-USB-HS, a GPIB to USB converter to connect a Tektronix TDS 2022 to the PC running LabVIEW. Don't forget that this particular converter, or similar products manufactured by other vendors, also needs special drivers. NI provides proprietary drivers for GPIB-USB-HS (found on http://www.ni.com/). A GPIB to UB converter is also available from HP (Agilent) that may be used directly in LabVIEW:
