Analog Output Data Generation Methods
When performing an analog output operation, you can perform software-timed or
hardware-timed generations.
Software-Timed Generations
With a software-timed generation, software controls the rate at which data is generated. Software
sends a separate command to the hardware to initiate each DAC conversion. In NI-DAQmx,
software-timed generations are referred to as on-demand timing. Software-timed generations are
also referred to as immediate or static operations. They are typically used for writing a single
value out, such as a constant DC voltage.
