规格表1列出了空载固态铯束频标的规格。准确度、精密度和稳定度的定义现已标准化。准确度指设备之间的差,精密度指单个设备的重调性,两者都不依靠任何外部标准而独立校准。长期稳定度是根据几个相隔24小时以上的15分钟取样时间的平均值得出的,短期稳定度是根据1秒平均时间得出的。 Specifications Table 1 lists the specifications of the no-load solid-state cesium beam frequency standard. The definitions of accuracy, precision and stability are now standardized. Accuracy refers to the difference between devices, precision refers to the re-modulation of a single device, both independently calibrated without any external standards. Long-term stability is based on the average of several 15-minute sampling intervals over 24 hours. Short-term stability is based on a one-second average time.
