A bit-error-rate (BER) test is a crucial test for wireless devices to pass, since a device with a high BER does not perform at its best. BER tests are both costly and difficult to perform due to a delay incurred by the device under test (DUT) 215 and the testing hardware that is variable in nature. Because the delay is variable, a hardware BER test that can compensate for the delay is difficult to build and a software BER test that can easily compensate for the delay is very slow. The present invention provides a method and apparatus that can compensate for the variable delay. By doing so, a hardware BER test, which is considerably faster than a software BER test, is easily implemented.
