The invention pertains in general to the testing of the operation of radio and other data transmission apparatus. In particular the invention pertains to the testing of the operation of a digital radio apparatus on the basis of error statistics. In order to test functions relating to data transmission, a simulation system produces a pseudorandom bit sequence or some other test sequence which is packed into downlink frames and sent to the data transmission apparatus tested. In accordance with the invention, a known number of errors are generated in the test sequence. As the data transmission apparatus tested compares the received test sequence to the sequence it has produced, it detects the errors in the received sequence and compiles various error statistics, e.g., in the form of bit error ratio (BER) or frame erasure ratio (FER). An uplink connection is used to send these statistical data to the simulation system which examines whether the information produced by the data transmission apparatus tested matches the simulation system's information about the erroneousness of the sequence sent downlink.
