Patent ID: 8841923

Claim:
A system for measuring a property of a device under test (DUT), the system comprising: a stimulus signal generator configured to generate a repetitive stimulus signal under control of a first clock, and to provide the stimulus signal to an input port of the DUT; and a receiver configured to receive an input signal from an output port of the DUT, the input signal being based on the stimulus signal provided to the input port of the DUT, the receiver comprising: a second clock syntonized with the first clock, such that a second frequency of the second clock is the same as or derives from a first frequency of the first clock without synchronizing to the first clock; a memory configured to store a calibration measurement of a calibration stimulus signal provided to the receiver during a calibration period without the DUT being connected to the stimulus signal generator; and a data processor configured to determine the property of the DUT based on the stored calibration measurement and a measurement of the input signal from the DUT performed under control of the second clock.
