An Analysis of a Microprocessor Controlled Disciplined Frequency Standard,
Abstract
This paper summarizes the ideas, experiments and conclusions from an effort to develop a new, producible disciplined quartz frequency standard. Some of the original thinking comes from a paper published in the late sixties which described the use of a third order phase locked loop (PLL) system to fully correct a drifting frequency source. Further, the paper described the behavior of the corrected frequency source when the PLL was without reference input, or coasting, and showed that much of the drift had been effectively removed by the third order control. These results lead to the development at Austron of the model 2010B Disciplined Frequency Standard. The objective here is to implement this same idea at the current state-of-the-art, taking advantage of the power and versatility of the microprocessor.
