Abstract A noise temperature alarm of Shaoguan CINRAD/SA weather radar occurred at 2012-03-05T03:53.When the deviation values of the CW and RFD calibration increase, the SYSCAL value also increases and linear channel gain calibration constant appears abnormal.According to analyze the faults by steps, the reason that caused the faults is the loose connection of two state switch.Then, its solutions are put forward in time.

Key words： CINRAD/SA system noise temperature two state switch linear channel gain calibration constant
