| Abstract: | A new chip microprocessor servo developed in our lab. is introduced in de- tail in the paper. Concerned paramaters are displayed on a LCD with 4 coluums x 40 words. lt has practical and commomly used features and the functions can be expanded eas- ily. We have used it for a cesium atomic clock to investigate concerned performances and found that the servo is able to improve clock's reproducibility, stability and accuracy. To fit in with the requirements of high performance clock and primary standard, the author pro- poses a tentative.idea of multiple control using the chip-microprocessor servo. |
