A method for calibrating a semiconductor test instrument leading cost reduction, simplified work, and short working time. Drivers are related to comparators in one-to-one correspondence. A clock signal and a strobe signal have a one-to-one correspondence. The phase of either a clock signal or a strobe...http://www.google.de/patents/US7111490?utm_source=gb-gplus-sharePatent US7111490 - Method for calibrating semiconductor test instruments
