What Is an RF Positioning System?

An RF positioning system is a precision motion platform designed to accurately move or rotate a device under test (DUT) during RF and antenna measurements. By controlling movement with high accuracy, the system allows engineers to capture complete radiation patterns, antenna gain, and wireless performance data from multiple orientations.

Unlike manual positioning methods, automated positioning systems deliver consistent movement throughout every test cycle, reducing measurement errors and improving overall reliability.
