  • Patent number: 6137830
    Abstract: A system (100) for measuring bit error rate performance of a radio device by the radio device and conveying measurement acoustically includes a test controller (102), a pattern generator (104), a radio frequency signal generator (106), an audio receiver (108), and a test environment cell (110) containing the radio device under test, or DUT (112), such as a selective call device. The radio device includes a radio frequency receiver (113), a sound generating device (122), a memory (118) having a pre-stored digital pattern, and a microprocessor (120) for decoding a received digital pattern. The microprocessor decodes the received digital pattern, compares the received digital pattern with the pre-stored digital pattern, calculates a bit error rate, and controls the sound generating device to produce an audible signal indicative of the bit error rate. The test controller correlates the bit error rate with a radio frequency sensitivity level.
