摘要： An RF chain having a high-frequency oscillator providing first, second and third outputs. The first output is multiplied to provide a microwave signal to an atomic beam tube; the second output is divided to provide a standard output frequency; and the third output is divided to provide a first input to a phase detector. The phase detector receives a second input from a low-frequency oscillator which is controlled by a servo signal from the atomic beam tube. The output of the phase detector provides a control signal to the high-frequency oscillator.

摘要： An electro-optic delay line frequency discriminator has an optical signal source providing first and second optical signals that are directed along first and second paths, respectively. In the first path, the first optical signal is converted to a first corresponding optical signal that corresponds to an electrical input signal, and the first corresponding optical signal is then delayed. In the second path, the second optical signal is delayed, and the delayed second optical signal is then converted to a second corresponding optical signal that corresponds to the electrical input signal. The first and second corresponding optical signals are converted to first and second corresponding electrical signals, respectively; and a detector, responsive to the first and second corresponding electrical signals, provides an electrical output signal from the discriminator. Optical source relative intensity noise (RIN) is canceled out and does not degrade the signal-to-noise ratio of the discriminator output.
摘要翻译：电光延迟线鉴频器具有分别提供沿着第一和第二路径引导的第一和第二光信号的光信号源。在第一路径中，第一光信号被转换成对应于电输入信号的第一对应的光信号，然后第一对应的光信号被延迟。在第二路径中，第二光信号被延迟，然后延迟的第二光信号被转换成对应于电输入信号的第二对应的光信号。第一和第二对应的光信号分别被转换成第一和第二相应的电信号; 并且响应于第一和第二对应电信号的检测器提供来自鉴别器的电输出信号。光源相对强度噪声（RIN）被抵消，并且不会降低鉴别器输出的信噪比。
