Abstract:
1. A testing system for testing first and second battery-powered electronic devices-under-test (DUTs), comprising: first and second transport frames for receiving the first and second DUTs, the first transport frame including a first transport frame power supply and a first switching circuit, the second transport frame including a second transport frame power supply and a second switching circuit; a test fixture arranged to receive the first and second transport frames and to test the first and second DUTs, respectively, when the first and second transport frames are engaged with the test fixture, the test fixture including a test fixture power supply; and a switching controller in communication with the first and second switching circuits and arranged to generate first and second power switching signals; the first switching circuit arranged to switch from the first transport frame power supply to the test fixture power supply in response to receiving a first power switching signal indicating satisfaction of the pre-testing condition, and arranged to switch from the test fixture power supply to the first transport frame power supply in response to receiving a second power switching signal indicating completion of a testing stage for the first DUT, the switching controller arranged to initiate power switching of power supplied by the test fixture power supply from the first transport frame to the second transport frame to begin a testing stage for the second DUT, the second switching circuit arranged to switch from the second transport frame power supply to the test fixture power supply in response to receiving a third power switching signal indicating satisfaction of a second pre-testing condition, and arranged to switch from the test fixture power supply to the second transport frame power supply in response to receiving a fourth power switching signal indicating completion of the testing stage for the second DUT, the switching controller arranged to generate the third and fourth power switching signals.
