Claim Text:
1. An automatic tester, comprising: a first signal converter operable to convert, using a conversion clock signal, a signal from a digital signal domain to an analog signal domain to acquire an analog stimulus signal; a first signal path operable to forward the analog stimulus signal from the first signal converter to a second signal converter operable to convert the analog stimulus signal back from the analog signal domain to the digital signal domain; and a second signal path operable to forward one of the conversion clock signal and a signal derived thereof from the first signal converter to the second signal converter, wherein a difference between a propagation delay of an analog stimulus signal in response to a clock cycle of the conversion clock signal via the first signal path and a propagation delay of the conversion clock signal of the clock cycle via the second signal path is within a predetermined tolerance range.
