Evaluation of ADC Testing Systems Using ADC Transfer Standard

摘要

A transportable high-stability reference AD device was designed and built to compare the systems for testingthe dynamic quality of analog-to-digital converters (ADCs) or analog-to-digital (AD) modules. Three different input modules can be used in the frequency range up to 5 MHz. First, this paper refers to the results of an AD device application in the frequency range of the testing signal up to 100 kHz, where four ADC testing systems were compared in different laboratories, and a short time amplitude and/or frequency instability of testing signal generators was evaluated. Second, it describes the first experiellce of its application in the frequency range from 100-5 MHz.
