Data Acquisition and Signal Conditioning
Overview
Using LabVIEW, data acquisition devices, and signal conditioning hardware, the Data Acquisition and Signal Conditioning course teaches you the fundamentals of PC-based data acquisition and signal conditioning. During the course, you get hands-on experience installing and configuring data acquisition hardware and you learn to use data acquisition software functions to build your application. Although LabVIEW is the application software used during the class, non-LabVIEW users using the NI-DAQmx API will also benefit by learning about analog input, triggering, analog output, digital I/O, counters, signal conditioning, and synchronization.

Duration Two (2) Days
