In this paper, a system is presented, which accurately synthesizes and coherently samples sinusoidal signals. The system, based on an atomic clock which disciplines both a signal generator and a data acquisition board, has been used to analyze the code excitation statistics of a coherently sampled sinewave, as a function of the selected sinewave parameters, including overdrive and initial phase. Experimental verifications have been carried out, aimed at investigating the problem of designing efficient stimuli for ADC testing purposes.

Abstract
In this paper, a system is presented, which accurately synthesizes and coherently samples sinusoidal signals. The system, based on an atomic clock which disciplines both a signal generator and a data acquisition board, has been used to analyze the code excitation statistics of a coherently sampled sinewave, as a function of the selected sinewave parameters, including overdrive and initial phase. Experimental verifications have been carried out, aimed at investigating the problem of designing efficient stimuli for ADC testing purposes.File in questo prodotto:
