Overview
Analog output (AO) devices convert digital data stored on the computer to a real-world analog signal. These devices perform the inverse conversion of analog input (AI) devices. Typical plug-in acquisition boards offer two output channels with 12 bits of resolution, with special hardware available to support multiple channel analog output operations. The functionality related to the analog output process allows you to send digitally represented data out of the computer system as an analog output signal. The Data Acquisition Toolbox provides access to analog output devices through an analog output object. The purpose of this chapter is to show you how to perform analog output data acquisition tasks. In presenting these tasks, only the properties and functions that are specific to analog output objects are presented. If at any time you want more information about any property or function, you can refer to the appropriate reference section in this book or the command line help. To learn more about basic toolbox functionality, you should refer to Chapter 2, "Data Acquisition Toolbox Concepts."
