Generating a Signal

  • Generating a Signal With Your Computer
    Use a USB data acquisition device to generate signals with your computer and NI LabVIEW.

Before You Begin

Learning to receive signals is just the beginning. It is also important to understand how to send signals to motors, actuators, and indicators so you can communicate with the real world and automate tasks. An example of this is sending a varying analog voltage to a DC motor to power a fan. This requires a digital-to-analog converter to output the signal to the real world. This module covers creating and outputting an analog signal on a DAQ device using NI LabVIEW software. Prior to starting this module, review the Learn LabVIEW modules to understand the fundamentals of graphical programming.
