Abstract

To characterize the performance of solid-state voltage standards (Zener standards) the 1/f nature of Zener noise must be considered. At the Bureau International des Poids et Mesures (BIPM) this is done by using the Allan variance to take into account correlation in serial measurements by specifying the limit of precision quanitified by the constant value called the 1/f noise floor taken on by the Allan variance. This paper discusses two methods to determine the noise floor of Zener standards of the National Institute of Standards and Technology (NIST) using either a Josephson voltage standard to measure a single Zener or by comparing two Zener standards. Results for two types of Zener standards are presented.
