Abstract

A testing device comprises a transmission path comprising at least one leakage conduction antenna disposed in the cabin of the aircraft, a control device coupled to the transmission path, said control device comprising a generating device for generating a broad-band interference signal and a transfer device for feeding an HF signal to the leakage conduction antenna, wherein the fed HF signal has a pre-defined power level and contains at least the generated broad-band interference signal, at least one measuring device coupled to the transmission path at a pre-defined coupling point, said measuring device measuring the power level of the HF signal at the coupling point and preparing a measurement signal that is proportional to the measured power level, and an evaluation means for preparing a test result by way of a comparison between the prepared measurement signal and a target signal that depends on the power level of the fed HF signal.
