Abstract: | A setup that includes a digital synchronous detector and a digital frequency control loop and is designed for use in a cesium beam frequency standard is described. It is based on the TMS 32010 signal microprocessor. When associated with a high-quality HP 5061A option four cesium beam tube, it makes it possible to achieve the same levels of short-term and medium-term frequency stability as its original analog counterpart. It is thus expected that the setup will fit the improved short- and long-term frequency stability capability of optically pumped cesium beam tubes |
