Abstract

The invention discloses an electromagnetic compatibility test analysis method and a corresponding electromagnetic compatibility test system. according to the electromagnetic compatibility test analysis method, multi-stage superheterodyne sweep frequency analysis is carried out on an imported time-domain signal by means of integrated software to obtain various frequency spectra of the signal, and therefore whether the signal meets the requirements for electromagnetic compatibility or not can be judged quickly according to a difference value between the frequency spectra and a test standard limit value. Compared with the prior art, the electromagnetic compatibility test analysis method has the advantages of short analysis time, simple operation, low cost and wide application range, and effectively improves the electromagnetic compatibility design efficiency.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electromagnetic compatibility test analysis method and a system thereof. Background technique [0002] Electromagnetic Compatibility (Electro-Magnetic Compatibility, referred to as EMC) means that electrical and electronic products can work normally in an electromagnetic environment without causing excessive electromagnetic interference (Electro-Magnetic Interference, referred to as EMI) to other products in the environment, which includes There are two requirements: one is that the product is required to have a certain tolerance to external electromagnetic interference; the other is that the electromagnetic interference generated by the product to the surrounding environment during normal operation cannot exceed a certain limit. [0003] With the continuous development of automotive electronic technology, the proportion of automotive electronic equipment in electronic and...
