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.
