TEST DEVICE AND METHOD FOR CARRYING OUT A FUNCTIONAL TEST OF A COMMUNICATION SYSTEM

摘要

The present invention provides a test device and a method for carrying out a functional test of a communication system. The test device contains a transmission path which comprises at least one leaky line antenna arranged in the aircraft cabin, a control device which is coupled to the transmission path and comprises a generating unit for generating a broadband noise signal and a transmission unit for feeding a HF signal to the leaky line antenna, the fed HF signal having a predetermined power level and containing at least the generated broadband noise signal, at least one measuring unit which is coupled at a predetermined coupling point to the transmission path for measurement the power level of the HF signal at the coupling point and for provision of a measuring signal which is proportional to the measured power level, and an evaluation means for providing a test result by comparing the measuring signal provided and a setpoint signal which is dependent on the power level of the fed HF signal.
