Analog Signal Generation

Configure analog output channels and generate signals with your device

Before you use analog output channels, see Hardware Discovery and Setup.

Functions

`addoutput`	Add output channel to device interface (Since R2020a)
`write`	Write output scans to hardware channels (Since R2020a)
`preload`	Queue scan data for device output (Since R2020a)
`flush`	Flush DataAcquisition input and output buffers (Since R2020a)
`readwrite`	Simultaneously read and write device channel data (Since R2020a)
`start`	Start DataAcquisition background operation (Since R2020a)
`stop`	Stop background operation (Since R2020a)
`removechannel`	Remove channel from device interface (Since R2020a)

Generate Continuous and Background Signals Using NI Devices

Generate analog output data using non-blocking commands. This allows you to continue working in the MATLAB command window during the generation. This is called background generation. Use foreground generation to cause MATLAB to wait for the entire data generation to complete before you can execute your next command.
