FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used to perform functional check of a communication system in an aircraft cabin. The apparatus for functional check of a communication system comprises a control device which includes a broadband noise signal generator and a transmitter for transmitting a high-frequency signal to a radiating linear antenna, wherein functional check is performed at a power level so low that signal emission at the radiating linear antenna is lower than a given limiting value outside the cabin.
EFFECT: reduced interference for services outside the aircraft.
