摘要：

Comparing high-performance frequency standards often requires making comparisons over displacements in time and/or space. The uncertainties introduced into comparisons made with dead time or with displacements in time are discussed. The estimates of uncertainty are based on the noise characteristics of an ensemble of cavity-tuned hydrogen masers used as a stable frequency reference. Specific examples are given.
