PURPOSE:To efficiently analyze the performance of an automobile radio by applying a test signal for reproducing a radio frequency broadcast signal received by a receiver which is moving, in a prescribed place. CONSTITUTION:A vehicle 10 is moved in an area for receiving a broadcast signal 15, a high frequency broadcast signal 15 from antennas 12, 13 installed on the vehicle 10 is applied to a recorder 11, and the broadcast signal 15 is recorded in a recording medium 25. Subsequently, the recording medium 25 is carried to a prescribed place, and the recorded broadcast signal 15 is reproduced as a high frequency input of a radio equipment to be tested. It is desirable that the broadcast signal 15 is obtained from plural antennas 12, 13 on the vehicle 10, and signals from each antenna 12, 13 are recorded exactly by the recorder 11. In such a way, the performance of an automobile radio can be analyzed efficiently. |
