                 With the emergence of high performance hydrogen clock (6E-14/s), the traditional phase microleap meter (typical short-term stability: 2E-13/s) has greatly limited the short stability of hydrogen clock signal and become the short board of frequency regulation of the clock group, so that the performance of hydrogen clock cannot be fully developed. The STHMS-10, a high performance microleap meter developed by Chengdu Tongphase Technology, has a short-term stability of<6E-14/s and a minimum frequency resolution of 9E-20, which can ensure the precise regulation of the hydrogen clock frequency without affecting the short-term stability of the hydrogen clock, and is the best choice for the frequency regulation of the high performance clock set.
