Abstract

The invention belongs to the technical field of airborne equipment testing, and particularly relates to a power line audio conduction sensitivity testing mode switching device for airborne equipment. In the embodiment of the invention, the device is provided with a power supply switching switch S1, a capacitor switching switch S2 and a mode switching switch S3, so that rewiring during switching among different testing modes is avoided; the testing time is saved; the workload is lowered; and the equipment loss is reduced. Moreover, a test circuit is arranged in a control box, so that the electric shock hazard caused by a naked circuit terminal is avoided.

Description

technical field [0001] The invention belongs to the technical field of airborne equipment testing, and in particular relates to a mode switching device for an audio frequency conduction sensitivity test of an airborne equipment power line. Background technique [0002] In order to ensure that airborne equipment can operate reliably after being installed on the aircraft, relevant international organizations have formulated a series of minimum standard environmental test conditions (categories) and corresponding test methods to verify airborne equipment under harsh external environmental conditions. The more influential aviation standard research organizations include the American Radio Commission for Aeronautics (RTCA) and the European Civil Aviation Electronics Organization (EUROCAE). After negotiation, a consensus was reached on environmental conditions and test methods, which are not only widely recognized in the international aviation field, but also often used as the bas...
