TESTING DEVICE

摘要

A test device includes: the first reference clock generation unit for generating the first reference clock; the first test rate generation unit for generating the first test rate clock based on the first reference clock; the first driver unit for supplying the first test pattern to an electronic device based on the first test rate clock; the second reference clock generation unit for generating the second reference clock; the first phase synchronization unit for synchronizing the phase of the second reference clock with the phase of the first test rate clock; the second test rate generation unit for generating the second test rate clock based on the second reference clock having the synchronized phase; and the second driver unit for supplying the second test pattern to the electronic device based on the second test rate clock.
