Explore the fundamentals of data acquisition using sensors, NI data acquisition hardware, and LabVIEW. Learn the basics of hardware selection, including resolution and sample rate, and the foundations of sensor connectivity, including grounding and wiring configurations. Use the NI-DAQmx driver to measure, generate, and synchronize data acquisition tasks. Program finite and continuous acquisitions, as well as best practices in hardware/software timing, triggering, and logging.
Data Acquisition Using NI-DAQmx and LabVIEW is available to PHYS 318 students as part of the LabVIEW Student License.
