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 system (DMTD). But, the limitation makes the measurement complex and inconvenient. In this paper, a high-precision time-frequency measurement system is constructed based on the device of TSC MMS. It is used to evaluate the ability of remote monitor and characteristic test through internet for precise frequency source. It can measure and compute the frequency difference and frequency stability automatically, graphically and intelligently. Moreover, a method of autonomous integrity monitoring for system is proposed and verified. This system has been adopted in some real high-precision measurement experiments. The system can meet the measurement requirements well and its noise floor is 2.5E-13(10MHz).
