A Bridge Circuit for the Dynamic Characterization of Sample/ Hold Amplifiers

A transformer bridge technique is described for measuring the dynamic performance of sample/hold amplifiers (S/H´s). The technique accurately measures dynamic gain errors, signal delay, aperture time delay and jitter, and acquisition time. These parameters are of particular importance to simultaneous data acquisition. The bridge is self-calibrating, and the voltage and time resolution are primarily limited only by the oscilloscope which serves as a detector.
