Abstract :
A new testing method has been used to evaluate the dynamic performance of several digitizing systems used in nuclear physics experiments. This recently introduced method allows the determination of the signal to noise ratio of the converter, not including its harmonic distortion, using an excitation signal noisier than the digitizer quantization noise. This quality makes it specially useful to evaluate the dynamic performance of high resolution analog to digital converters. The immunity of the method to non-coherent sampling and its behaviour in the presence of jitter errors are emphasised
