PURPOSE: To accurately and easily perform adjustment with a simple adjustment equipment by adjusting the adjustment element of a radio receiver in accordance with the output state of a signal meter signal. CONSTITUTION: With respect to a tuner pack 25, a tuning circuit 12, an electric field intensity detection circuit 18, etc., are integrated and stored in a metallic case or the like, and a connection terminal 26 for connection to a peripheral circuit is provided. A measurement terminal 38 of an adjustment device 30 is connected to an S meter signal output terminal 27 of this tuner pack. The modulated output signal of a standard signal generator is inputted to the antenna input terminal of an FM stereo receiver to be adjusted through a dummy antenna 31. A microcomputer 21 operates an actuator 32 in accordance with the program stored in a ROM to adjust respective adjustment elements of the tuning circuit 12, a high frequency amplification circuit 13, and an intermediate frequency amplification circuit 16 so that the S meter signal has a maximum value. The S meter signal is a DC signal, and the automation system is easily constituted. |
