Easy Estimation of Spectral Purity of Test Signals for ADC Testing

Original language description

ADC testing frequently confronts the problem of spectral purity of harmonic test signal. The majority of dynamic ADC test methods require test signal distortion at least 10 dB less than that of the tested ADC - the condition that cannot be practically fulfilled for testing up-to-date ADCs. More sophisticated approach to ADC testing applies the correction for test signal imperfections. In both cases test signal distortion has to be known - roughly in the first case and quite accurately in the second case. In this paper an easy method for the testing of signal spectral purity is proposed. Test signal passed by one of two simple analog filters is measured by a common ADC, whose nonlinearity is mathematically post-corrected. The results are compared with common approach applying notch filter and uncertainty analysis is performed.
