MAGNETIC STEERING APPLICATION FOR SINGULATED (X)MR SENSORS

摘要

A controller for a test head module (106) of a test cell (100) includes a control signal generator, an electronic memory device, and a signal evaluation module. The control signal generator to provide control signals to a plurality of magnetic stimulator heads, which provide magnetic stimulus signals to singulated devices for testing in response to the control signals. The electronic memory device stores instructions for controlling concurrent activation of at least two of the magnetic stimulator heads for parallel testing of the singulated devices. The signal evaluation module receives electrical signals from the singulated devices. The electrical signals from the singulated devices are dependent on the magnetic stimulus signals applied to the singulated devices.
