Data Acquisition Toolbox

Getting Started with Analog Input

Analog input (AI) subsystems convert real-world analog input signals from a sensor into bits that can be read by your computer. Perhaps the most important of all the subsystems commonly available, AI subsystems are typically multi-channel devices offering 12 or 16 bits of resolution. The Data Acquisition Toolbox provides access to analog input devices through an analog input object.

The purpose of this chapter is to show you how to perform simple analog input tasks using just a few functions and properties. After reading this chapter, you should be able to use the Data Acquisition Toolbox to configure your own analog input session. Topics include:

• Creating an analog input object
• Adding channels to an analog input object
• Configuring analog input properties
• Acquiring data
• Analog input examples
• Evaluating the analog input object status
