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.

Staircase signal (Oscilloscope version)


We will attempt to duplicate the preceding example, this time using an oscilloscope. Here, we will be controlling an oscilloscope remotely. There should be little need to explain why it is necessary to be able to control an oscilloscope with LabVIEW. Aside from the actual various measurements that an oscilloscope can provide (beyond the scope of this book), it is essential to know how to connect to and use a given oscilloscope as one of the most important test and measurement instruments in use. When choosing an oscilloscope to automate and/or acquire data using LabVIEW, a few points are essential:

  • Price

  • Ability to be remotely controlled (Serial, Parallel, GPIB, Ethernet, and so on)

  • Controlling protocol and driver software

Obviously, hardware products from National Instruments (NI) are most suitable for this purpose. But there are many occasions that certain required hardware is not available through NI. There are also other reasons that makes third-party...
