Temperature influence on the establishment of a digital voltage reference

摘要

This paper describes the experimental set-up and results obtained on the evaluation of the temperature influence of the main components of a digital voltage set-up. In particular, the phase displacement between two 3458A digital multimeters as a function of temperature for different aperture times and the characterization of a resistive voltage divider prototype, including the frequency response, phase displacement and amplitude variation as a function of temperature.
