The invention relates to a method and to a test device ( 12 ) which is used to determine an error rate during the transfer of data ( 1 ) in a mobile radio system. Said mobile radio system comprises at least one transfer channel, wherein several data partial flows ( 2.1, 2.2, 2.6 ) are transferred. The several data partial flows ( 2.1, 2.2 . . . 2.6 ) are produced in a signal generator unit ( 8 ). A transport format is determined, in an individual manner, for each data partial flow ( 2.1, 2.2 . . . 2.6 ). The data partial flows ( 2.1, 2.2 . . . 2.6 ) are sent, respectively, to a number of transfer blocks which belong together ( 5.1, . . . 7.1 ). A device which is to be tested captures the transfer blocks ( 5.1, . . . 7.1 ) of the data partial flows ( 2.1, 2.2 . . . 2.6 ) and evaluates them. According to the accuracy of the evaluation, a positive or negative actuation signal (ACK, NACK) is sent back by the device which is to be tested. An error rate of each data partial flow ( 2.1, 2.2 . . . 2.6 ) is determined by the test device ( 12 ) from the actuation signals (ACK, NACK) which are captured by the test device ( 12 ).
