A testing front end module for testing a plurality of devices under test (DUT) includes a testing signal interface, a vector signal generator (VSG) coupled to the testing signal interface and configured to generate testing signals upon reception of testing routine signals from a remote controller via the testing signal interface, a vector signal analyzer (VSA) coupled to the testing signal interface and configured to receive testing response signals from a plurality of DUTs and to transmit the received testing response signals to the remote controller via the testing signal interface, a multiplexer/demultiplexer (MUX/DEMUX) coupled to the VSG and the VSA, the MUX/DEMUX being configured to multiplex the received testing response signals and to demultiplex the generated testing signals, and a test device interface coupled to the MUX/DEMUX and configured to couple the testing front end module to the plurality of DUTs.

A method and tester for determining the error rate of a mobile radio device with variable block allocation is provided. Transmission blocks are sent to a mobile radio device to be tested. The mobile radio device to be tested receives and evaluates the transmission blocks and transmits a first and a second qualifier (ack, nack), respectively, for every transmission block correctly or not correctly evaluated. The number of transmission blocks sent to the mobile radio device to be tested and that are not correctly evaluated by the device is determined, and an error rate is determined, the number of transmission blocks being variably set by multiblocks that address the mobile radio device to be tested between one transmission block per multiblock and all transmission blocks of the multiblock and one multiblock comprising a fixed number of transmission blocks.
