Abstract： This paper briefly introduces the working principle of the excitation module of communication equipment. Aiming at the problem of self inspection and accidental fault reporting of a batch of excitation modules， through the detailed analysis of the fault causes， it is found that the sampling time is critical to the effective time of the indication signal. It is proposed to find the best sampling time period on the premise of the indication signal， the solution to optimize the design of software sampling time.

Key words： built in test; fault tree; response time; sampling
