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.
