ABSTRACT:
A radio communication apparatus (21) is tested by radio and optical test signals (RTS and OTS) simultaneously transmitted by a test transmitter (22). Each test signal carries a test digital data signal. The apparatus has a radio digital data recovering section (23-25) for recovering the test digital data signal as a first digital data signal from the radio test signal. An optical digital data recovering section (39-42, 44-46) recovers the test digital data signal as a second digital data signal from the optical test signal. A comparing section (48-52) produces a bit coincidence signal whenever corresponding bits between the first and the second digital data signals coincides with each other. A counter (54) counts up a count to an increased count in response to the bit coincidence signal during a predetermined time interval. An indicator (30-32) indicates the increased count as sensitivity of the apparatus.
