The invention discloses a comparison device for magnetic field radiation sensitivity testing equipment, which includes: RS101 radiation antenna, used for radiating cable signals; Coupling, extraction and amplification of the cable signal radiated by the radiating antenna; measuring equipment, used to measure the size of the cable signal output by the comparison module. Amplify and monitor and display in real time through the spectrum analyzer. At the same time, a transient suppression and protection circuit is designed on the power line of the comparison device to protect the safety of the back-end spectrum analyzer and comparison device. Realize RS101 through coil mutual inductance The cable signal radiated by the radiation antenna is extracted, and non-magnetic materials and low magnetic permeability materials are selected for processing of the comparison device to minimize the impact on the uniformity of the radiation magnetic field.
Description
technical field [0001] The invention relates to the technical field of magnetic field radiation sensitivity testing, in particular to a comparison device for magnetic field radiation sensitivity testing (RS101) equipment. Background technique [0002] Electromagnetic compatibility is an important performance index of weapons and equipment, and it is one of the basis for the finalization of weapons and equipment. Electronic information technology has been widely used in the military, and the degree of informatization of weapons and equipment is getting higher and higher, making the electromagnetic environment faced by weapons and equipment increasingly complex. Electromagnetic compatibility issues such as electromagnetic interference and electromagnetic damage have become increasingly prominent. [0003] Existing foreign military standards for electromagnetic environmental effects mainly include US military standards, NATO standards, and European military standards such as th...
