Taking a Measurement

  • Taking a Measurement with Your Computer
    Learn how to use a USB data acquisition device to take measurements with your computer.

Before You Begin

Every day, scientists and engineers are required to perform tests. The signals that they measure are real-world analog signals that vary indefinitely with time. To automate and better visualize the data, you need to transfer the analog signal to the digital world to be viewed on a computer. Data acquisition devices, such as the NI myDAQ or NI Educational Laboratory Virtual Instrumentation Suite (NI ELVIS) II, perform analog-to-digital conversion to accomplish this task. This module shows you how to acquire an analog voltage signal using a DAQ device and NI LabVIEW software. Prior to starting this module, review the Learn LabVIEW modules to understand the fundamentals of graphical programming.
