Low Frequency Time Code Signal Flow and Fault Diagnosis

Abstract: low frequency time code timing is an important part of time service system in China, which is widely used for civil and military users. The transmitter used in low-frequency time code timing is also the only high-power solid-state low-frequency time code transmitter in China. In view of its importance and uniqueness, and the composition of the low-frequency transmitter is extremely complex, the components are very many, and the correlation of each component is very strong. Therefore, in the equipment operation, the daily maintenance of low-frequency transmitter is very important, However, there are few related introduction and related technical materials. The purpose of this paper is to summarize the operation and maintenance experience of low-frequency transmitter for many years, analyze the signal flow and related carrier composition of low-frequency transmitter, systematically describe the relevant work flow of low-frequency signal, analyze the relevant signal fault phenomenon, and summarize the methods to solve the corresponding fault, so as to provide relevant technology and experience for the follow-up equipment operation and maintenance work.
