Abstract

PURPOSE:To decide whether or not a receiver high frequency part is normal by impressing the leak electric power of a sent signal to the receiver high frequency part at transmission time and comparing its output with a reference value. CONSTITUTION:The operation of a transmission system is the same as before at the transmission time. This device puts the receiver high frequency pat 5 in an operation state even at this time. The leak electric power of the sent signal generated among terminals (a)-(c) of a transmission/reception switch 2, on the other hand, is inputted to the high frequency part 5, amplified, and led out by a directional coupler 6. Then the sent signal is detected by a decision circuit 7 and compared with the reference value. When the high frequency part 5 is faulty, its input/output characteristics are greatly different from those in normal operation, so it can be decided whether or not the high frequency part is normal. Consequently, the quality of the high frequency part 5 is decided.
