Abstract

The invention relates to the technical field of electronic equipment test and evaluation, and discloses a method and a piece of equipment for testing and evaluating the electromagnetic environment adaptability of electronic equipment. According to the adopted equipment for testing and evaluating the electromagnetic environment adaptability of electronic equipment in the method, n analog signal sources with electromagnetic environment factors are connected with a piece of electronic equipment to be evaluated through a signal synthesis circuit, the electronic equipment to be evaluated is connected with an electromagnetic environment adaptability evaluating device through a data transmission cable, and the signal synthesis circuit is connected with the electromagnetic environment adaptability evaluating device through a data transmission cable. Reasonable match between various electromagnetic environment signal factors and different level numbers can be sought, the number of tests can be reduced, data of capability of the electronic equipment to be evaluated in task completion under k<n> electromagnetic environments can be stored in a Flash data memory, and the electromagnetic environment adaptability of the electronic equipment to be evaluated can be calculated and evaluated. The evaluating device is applicable to the test and evaluation of the electromagnetic environment adaptability of electronic equipment like commercial radars and radios.

Description

technical field [0001] The invention relates to the technical field of electronic equipment testing and evaluation, in particular to a method and equipment for testing and evaluating the electromagnetic environment adaptability of electronic equipment. Background technique [0002] At present, the test and evaluation of the electromagnetic environment adaptability of electronic equipment has always been one of the recognized problems. The current evaluation method is mainly based on a large number of qualitative evaluations, supplemented by a small number of quantitative evaluations of the adaptability of a single factor in the electromagnetic environment; however, the actual performance of electronic equipment is affected by n electromagnetic environment factors, and the comprehensive performance of electromagnetic environment adaptability cannot be realized. Evaluate. Where n is generally a natural number greater than or equal to 2 and less than 10. The purpose of the pre...
