PURPOSE:To easily estimate a troubled part by storing the signal state of the radio device in a memory connected with a microcomputer and displaying it on a display or reading out the memory content by programs and the like. CONSTITUTION:A memory 4, a display device 6, and an interface 7 with a programmer are connected to a microcomputer 5 to which signals corresponding to the state change of a transmission output signal 1 is inputted through a detection circuit 2 and an A/D converter 3. It is sent from the microcomputer 5 to the memory 4, and displayed on the display device 6. It is read out to the programmer through the interface 7 with the programmer as needed. For example, in case of the fluctuation of the transmission output signal 1, the maximum and minimum values of the transmission output signal are stored in the memory. The power supply voltage 10 is inputted through a resistance voltage divider circuit 9 and an A/D converter 8 to the microcomputer 5. |
