Abstract
A measurement apparatus includes external terminals configured for connection to a device-under-test (DUT), the external terminals including first and second force terminals and first and second sense terminals. The measurement apparatus further includes a controller and a feedback loop configured in a current feedback mode to sense a current flowing from the first force terminal to the second force terminal, and in a voltage feedback mode to sense a voltage across the first and second sense terminals. The measurement apparatus further includes a measurement path configured to measure a least one of a voltage and current across a pair of the external terminals and to supply the measured at least one of the voltage and current to the controller.
