Abstract
Embodiments of the present application provide a time offset method and device for a test signal. When a signal source sends a test signal to a DUT on a test platform, the offset device can determine a time delay caused by impedance matching of the test signal to the DUT at the upper side of each test location, and conduct time offset for TCK signals sent by the signal source to different DUTs according to the time delay.
