EVALUATION OF SHORT-TIME INSTABILITY OF GENERATORS USED FOR ADC TESTING

Vladimír Haasz, Jaroslav Roztoèil, David Slepièka
  • Abstract:
    The quality of an evaluation of dynamic parameters of ADCs and AD modules is strongly dependent on the quality of testing signal generator. The most important parameters are the signal to noise ratio (SNR) and the spectral purity (THD). Besides, the short-time frequency and amplitude stability are also necessary to be considered, but it is often marginalized. However, they also influence the accuracy of the further evaluation. A possibility, how to estimate this imperfection, is presented in the paper.
