Data Acquisition Toolbox

Analog Output

Analog output subsystems convert digital data stored on your computer to a real-world analog signal. These devices perform the inverse conversion of analog input subsystems. 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 Data Acquisition Toolbox provides access to analog output subsystems through an analog output object.

The purpose of this chapter is to show you how to perform data acquisition tasks using your analog output hardware. Topics include:

• Getting started with analog output
• Managing output data
• Configuring analog output triggers
• Configuring events and actions
• Linearly scaling the data
• Starting multiple device objects

Example: Performing a Linear Conversion
