Reading and Writing Data with NI-DAQmx Simulated Devices

Last Modified: September 15, 2017

All NI-DAQmx simulated devices return analog input data in the form of a full-scale sine wave with 3% of full-scale noise. When multiple channels are in the task, the data for each channel is offset 5 ° in time. Digital data is always returned as if each eight-bit port were a binary counter. Counter data is always returned as 0.

Data written to an NI-DAQmx simulated device is scaled as if the device were real.
