ABSTRACT:
Providing reliable testing of a device under test (DUT) by compensating for a reduced voltage inside the device without changing the internal circuitry of the device. The DUT has multiple connection terminals for connecting to the test equipment including at least first and second power connection terminals that both connect to an internal power bus of the DUT. An adapter board connects to the multiple connection terminals of the DUT via a removably attachable socket which holds the DUT. A tester supplies power to the DUT through the adapter board. The adapter board is configured to supply power from the tester to the DUT through the first power connection terminal and to monitor voltage at the second power connection terminal. The tester includes a compensation unit which controls power based on the voltage monitored at the second power connection terminal.
