Abstract

Research, development and application of two unique instruments providing improved solutions to the problems encountered in the distribution, remote control and measurement of frequency stable, low phase noise standard signals are described. One of these is an Auxiliary Output Generator (AOG) providing remotely and locally controllable variation of frequency and phase with unprecedented resolution and low noise using a 5 MHz reference standard. The AOG provides the function of a continuously variable phase or frequency shifter as well as a synchronizable one pulse per second output. The second instrument is a Time Domain Measurement System (TDMS) including an internal offset generator so that stability, frequency and phase measurements can be made with exceptional precision without changing the frequency or phase of the source. Design concepts and applications of these instruments are described and measurement sensitivities are presented in conjunction with stability curves illustrating the performance of Sigma Tau Standards Corporation atomic hydrogen masers.

分配、遥控和测量频率稳定、相位噪声低的标准信号

描述了两种独特仪器的研究、开发和应用，为频率稳定、低相位噪声标准信号的分配、远程控制和测量中遇到的问题提供了改进的解决方案。其中之一是辅助输出发生器(AOG)，使用5 MHz参考标准，提供远程和本地可控的频率和相位变化，具有前所未有的分辨率和低噪声。AOG提供连续可变相位或移频器的功能，以及每秒可同步的一个脉冲输出。第二个仪器是时域测量系统(TDMS)，包括一个内部偏移发生器，因此可以在不改变源的频率或相位的情况下以极高的精度进行稳定性，频率和相位测量。介绍了这些仪器的设计概念和应用，并结合Sigma Tau标准公司原子氢脉泽性能的稳定性曲线介绍了测量灵敏度。
