Data Acquisition Toolbox

Getting Started with Analog Input

Analog input (AI) subsystems convert real-world analog signals from a sensor into bits that can be read by your computer. AI subsystems are typically multichannel 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 toolbox to configure your own analog input session. The sections are as follows.

Creating an Analog Input Object	Create a MATLAB object that represents the analog input subsystem
Adding Channels to an Analog Input Object	Associate hardware channels with the analog input object
Configuring Analog Input Properties	Define the object behavior by assigning values to properties
Acquiring Data	Execute the object and stream data from the hardware channels to memory
Analog Input Examples	Examples that show you how to perform a complete data acquisition task
Evaluating the Analog Input Object Status	Return the values of certain properties in a convenient display format
