| Abstract: | Semi-anechoic chamber is a simulated ideal environment,and it is undisturbed by electromagnetic interference.The electromagnetic wave is transmitted via free space in it.Radiated disturbance field measurement is performed in this particular environment.The theory for evaluating measurement uncertainty was introduced in this paper,the uncertainty sources for measuring radiated disturbance field were analyzed and evaluated,and the measurement uncertainty was presented according to the evaluated results.This paper can be guidance for electromagnetic compatibility（EMC） laboratory. |
