Abstract
An alternating current (ac) Josephson voltage source (Williams, et. al., 2002) was employed to characterize the dynamic behavior of a high-resolution 28-bit (8 frac12-digit) integrating analog-to-digital converter (ADC) of a digital sampling voltmeter (DSV), which is widely used in ac metrology at the Physikalisch-Technische Bundesanstalt - PTB. Extensive measurements were carried out to validate previous mathematical models of the DSV (Ramm, et. al., 1999) when sampling ac signals. Some measurement methods and results thereof are presented
