What is Data Acquisition?

Learn More About Data Acquisition

Data acquisition is the process of gathering or generating information in an automated fashion from analog and digital measurement sources such as sensors and devices under test. Data acquisition uses a combination of PC-based measurement hardware and software to provide a flexible, user-defined measurement system. Oftentimes, you must condition sensors and signals before a data acquisition device acquires them. Learn about conditioning signals including amplification, attenuation, and isolation.
