Chapter 3
Getting Started With Analog Input

Overview

Analog input (AI) devices convert real-world analog input signals from a sensor into bits that can be read by a computer. Perhaps the most important of all the devices commonly available, AI devices are typically multi-channel devices offering 12 or 16 bits of resolution.

The functionality related to the analog input device allows you to process an analog input signal and convert it to a digital representation for processing within the computer. 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 basic analog input data acquisition tasks. These tasks include:

Understanding these basic tasks will go a long way towards helping you understand the functionality and capabilities of the Data Acquisition Toolbox. In presenting these tasks, only a core set of properties and functions are used. If at any time you want more information about any property or function, you can refer to the appropriate User's Guide reference section or the command line help.
