PURPOSE: To perform a test while freely inputting voice data and to easily confirm the tested result in the case testing a speech path including the radio zone of a mobile communication system. CONSTITUTION: In the case testing the state of the speech path in the mobile communication system, the voice of test data is inputted from a microphone part 6 and applied to the mobile communication system, and an operation processing part 58 performs an S/N test based on the test data passed through a dropper 55 and data returned inside the mobile communication system and passed through a dropper 53 at such a time. Besides, a bit error test is performed based on the test data converted by a high-efficiency voice converting circuit 54 and extracted by the dropper 53 and data returned inside the mobile communication system and passed through the dropper 53 at such a time. Further, the data returned inside the mobile communication system are monitored by a speaker part 7. |
