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.

Oscilloscope functions in LabVIEW function pallets


Next, we need to make sure that software drivers are correctly installed in LabVIEW for the correct model of the instrument we have: the oscilloscope. Some vendors provide the software in the box with the hardware sold. Otherwise, a little search on the NI site will do the job. Usually, there are two flavors of the drivers for these devices: "Plug and Play" as well as "Plug and play (project style)". Complete and detailed installation is also available on the NI site. Note the path and two versions of the drivers installed. This is for demo and installation of both versions, while perfectly OK but not necessary useful. Note that if you are planning on making an application with an installer out of your VI(s), all drivers and non LabVIEW standard functions need to be included in the process of creating an installer for the application:

Once the software has installed properly, it will appear on your functions plug when you click on the Block...
