摘要
A rotating magnetic field Hall apparatus is provided and includes first and second magnets disposed in a master-slave configuration, a device-under-test (DUT) stage interposable between the first and second magnets on which a DUT is disposable in first or second orientations for Hall measurement or photoelectromagnetic (PEM) testing, respectively, controllers disposed to center the DUT stage between the first and second magnets and orthogonal magnetic field sensors disposed aside lateral sides of the first magnet to facilitate positional initialization of the first and second magnets and to generate in-phase and out-of-phase reference signals for phase-sensitive or lock-in Hall signal detection. The system also includes software system to perform signal processing to yield the final Hall signal.
