Abstract: A method for testing the (Bit) Error Ratio BER of a device against a maximal allowable (Bit) Error Ratio BERlimit with an early pass and/or early fail criterion, whereby the early pass and/or early fail criterion is allowed to be wrong only by a small probability F for the entire test. Ns bits of the output of the device are measured, thereby ne erroneous bits of these ns bits are detected. PDhigh and/or PDlow are obtained, whereby PDhigh is the worst possible likelihood distribution and PDlow is the best possible likelihood distribution containing the measured ne erroneous bits with a single step wrong decision probability D, which is smaller than the probability F for the entire test. The average numbers of erroneous bits NEhigh and NElow for PDhigh and PDlow are obtained. NEhigh and NElow are compared with NElimit=BERlimit ns. If NElimit is higher than NEhigh or NElimit is lower than NElow the test is stopped. Sequential sampling with two one-tailed parametric hypothesis test for the poisson distribution.

Abstract: A method and device for detecting an error rate of a receiver of data transmitted to a device that is to be checked is provided. A test device generates a data block having a first length and a test signal generated based on the data block is sent. The device to be checked receives and evaluates the test signal. Another data block having a different length is generated based on the evaluated test signal to obtain another data rate. The other data block is sent as a response signal in a different transmission direction, and is received and evaluated by the transmitter/receiver device of the test device. An evaluation unit compares the contents of both data blocks to detect the error rate, wherein the content of the shorter data block is compared with the content of a corresponding segment of the longer data block to determine the error rate.
