ABSTRACT:
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 signal is adjusted with reference to the phase of the other signal. The relative phase difference between clock signals or between strobe signals are determined. The phases of the clock and strobe signals are adjusted with reference to the relative phase difference.
