RESEARCH ON THE MEASUREMENT METHOD OF SHIELDING EFFECTIVENESS USING REVERBERATION CHAMBER

摘要

Regarding to the shortage of standard test methods for shielding effectiveness(SE) of small enclosure in reverberation chamber,a new testing system based on the statistic definition and multi-points measurements of SE has been successfully designed and developed.This system includes signal generator,power amplifier,shielding enclosure，field meter,motion track，step motor,control computer and software.It can be operateautomatically with data acquisition and treatment.This new system allows the tests at resonant frequencies of the enclosure and it can produce average and minimum values of SE tests.Experiments show that this new system can be applied as one of standard methods for SE measurements of small enclosure in reverberation chamber.
