The invention relates to a method for generating a signal train which can be played back on a tester for testing a mobile radio. First, a given command sequence is analyzed in respect of a signal train generated therefrom by the tester. The signal train which results from the command sequence is checked by comparing it with a standard-compliant signal train. Discrepancies between the standard-compliant signal train and the signal train resulting from the command sequence are detected and the necessary changes to the command sequence to generate a standard-compliant signal train are ascertained. In line with the necessary changes detected, commands or command sequence sections are supplemented and/or replaced. In this way, a command sequence which can be played back is generated and output.
