Patent ID: 8666392

Claim:
A method for testing devices of mobile-radio systems with the following method steps: generating signal data, generating a signal from the signal data by a signal generator, transmitting the signal to a device under test, receiving the signal by the device under test, evaluating the received signal and generating based on the evaluated received signal a response signal and transmitting the response signal, wherein the response signal provides a characteristic waveform of an envelope for information to be returned in the response signal, measuring the characteristic envelope and generating a test signal representing the waveform of the envelope in a measuring device, processing the test signal by the signal generator without a protocol tester, without a standardized demodulation of the response signal for retrieving the information, comparing the test signal representing the waveform of the envelope with at least one comparison signal by the signal generator to retrieve the information, and wherein in the event of an agreement of the test signal with the at least one comparison signal, assigning the test signal to a change command corresponding to the at least one comparison signal, reading in the change command, and generating sequence signals to be transmitted to the device under test and/or transmitting generated sequence signals to the device under test dependent upon an evaluation of the change command corresponding to the at least one comparison signal.
