  • [摘要]:Symmetricom's Multi-channel Measurement System (TSC MMS) is a phase measurement device based on the measurement principle of dual mixer time difference method (DMTD). TSC MMS is purchased by Time and Frequency measurement laboratory in National Time Service Center of Chinese Academy of Sciences. In order to evaluate the measurement capability of DMTD and research the improved method of performance, in this paper, the TSC MMS performance test platform is set up. We ensure the test signals have better stability than system, and the invariant environment to reduce the effect of measurement produced by external environment as much as possible. Under the same condition, three-day data are collected to measure the noise floor of a system. Finally, we analyze the reasons attributing to the measurement results and proposed a improving method in detail. The measured results demonstrate that the Allan deviation stability will reach 3E-13 per second when the frequency of the input signals is 10MHz.
