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.

Alternate Software for DAQ

Staircase signal (USB DAQ version)


In this example, the hardware connection is exactly the same as it was in chapter 3. That is, we will directly connect the signal generator to USB DAQ 6008. We will use Analog Input 1. However, the Signal generator is set to generate a Staircase signal in this example.

Launch LabVIEW and start a new VI from the file menu and continue with the following steps:

  1. Right click on the Block Diagram window and from Functions, select Measurement I/O, select NI-DAQmx and tack this pallet to the Block Diagram window. Now you can move this pallet to the appropriate location in your screen to make choosing and placing a Function on the Block Diagram and Front Panel windows with much ease and enhance the visibility of different windows. Note that when you move the mouse cursor on any Function icon, the complete name of the function is displayed. The same is true for each input and output of the any given function.
