Abstract

The invention provides an anechoic chamber and a using method thereof. The anechoic chamber comprises a bottom surface, first to fourth side walls, and a top surface. The first to fourth side walls encircle a frame body. Metal plates used for shielding electromagnetic waves are arranged outside the first to fourth side walls, the bottom surface and the top surface. Wave absorbing devices used for absorbing electromagnetic waves are arranged on the inner walls of the first to fourth side walls and the top surface. A first turntable and a second turntable used for placing a tested object are arranged on the bottom surface. First to third antenna towers which are movable and are used for assembling an antenna respectively are mounted on the bottom surface. The invention further provides a method for performing electromagnetic compatibility test by using the anechoic chamber. The anechoic chamber and the using method thereof of the invention meet the requirements of electromagnetic compatibility test of most products nowadays.

Description

technical field [0001] The invention relates to electromagnetic compatibility testing technology, in particular to an anechoic chamber and a using method thereof. Background technique [0002] Since Europe began to implement the electromagnetic compatibility standards of products, the radiation disturbance test of products has always been an indispensable part of electromagnetic compatibility testing. The anechoic chamber is the key test place in the electromagnetic compatibility test. In the method of product radiation disturbance test in the anechoic chamber, the maximum disturbance level and polarization direction of the product under test can be tested through the rotation of the turntable and the vertical height and polarization direction of the antenna. [0003] With the continuous development of electronic technology, the operating frequency of electronic products is becoming more and more diversified. The operating frequency or harmonic frequency of some electronic ...
