Evaluation of ADC testing systems using ADC transfer standard

A transportable high stable reference AD device was designed and built for a comparison of systems for testing of the dynamic quality of ADCs or modules. Three different input modules enable its use in the frequency range up to 5 MHz. First, this paper refers to the results of the AD device application in the frequency range of the testing signal up to 100 kHz (comparison of four ADC testing systems in different laboratories, evaluation of a short time amplitude and/or frequency instability of testing signal generators). Second, it describes the first experience of its application in the frequency range from 100 kHz to 5 MHz.
