Abstract

The invention relates to a tester for an over-the-air broadcasting device, and belongs to field of ground test for airborne equipment. When the over-the-air broadcasting device is mounted, a plane need to electrify the device to verify whether functions of the device are normal; however, the over-the-air broadcasting device electrified for a long time tends to damage hearing of people nearby due to the high output power. The tester provided by the invention can detect all the function of the over-the-air broadcasting device in a lab, as well as detect functions on a control box or loudspeaker independently.

Description

technical field [0001] The invention belongs to the field of ground testing of airborne equipment, in particular to an air broadcasting equipment tester. Background technique [0002] The air broadcasting equipment of the aircraft is not a necessary equipment for flight, and it does not affect the safety of flight. Its function is for the personnel on the aircraft to shout to the ground personnel when the aircraft is in the air, and to play the role of commanding, announcing, and driving away. Therefore, air broadcast equipment is an optional equipment, and because of its seldom application, there is almost no special equipment for its detection at present. [0003] After the air broadcast equipment is installed, the aircraft needs to be powered on on the ground to verify whether its function is normal, but the output power of the air broadcast equipment is relatively large, and it is easy to damage the hearing of nearby personnel if it is powered on for a long time.
