Design And Realization Of Radio Frequency Electromagnetic Field Radiated Susceptibility Auto Test System

In modern society,more and more electronic products bring us convenience while letting us face more and more odious electromagnetic pollution.Radio Frequency Electromagnetic Field Radiated Susceptibility test is such an effective test method that it can be used to check whether electronic products can word normally in “polluted ”environment.The test system can simulate actual electromagnetic environment and check the Susceptibility of equipment placed on a plane on which electric filed value of each point is equal.The design of the test system is based on the uniform field theory suggested by GB/T 17626.3-2006.Firstly,the test site(anechoic chamber)must be checked for the compliance with the requirement.Secondly,model of hardware setup is designed.According to the system requirement,technical parameters of each component can be established.Finally,programmable software was designed which can calibrated the whole system to check the uniformity of the electromagnetic field.Calibration data can be used by the software which can conducted the radiated susceptibility test automatically.Test efficiency and accuracy can be improved by the auto test system.The design of the test system was related to the practical application closely.The dissertation states the theory of design and work,requirement of hardware setup of the system.The problem encountered during the practical construction was pointed out and the solutions were illuminated.The dissertation is of guidance for actual manipulation.
