Microwave darkroom / shielding room

Summary: the microwave anechoic chamber is mainly used for the measurement of radiation radio disturbance (EMI) and radiation sensitivity (EMS). The size of the microwave anechoic chamber and the selection of RF absorbing materials are mainly determined by the overall size and test requirements of the EUT.

The whole anechoic chamber reduces the interference of the external electromagnetic wave signal to the test signal, and the electromagnetic wave absorbing material can reduce the multi-path effect caused by the reflection of the wall and ceiling on the test results, which is suitable for the emission, sensitivity and immunity experiments. It can simulate the situation of free space in the whole anechoic chamber. Compared with the other two test sites, the ground, ceiling and wall of the anechoic chamber reflect less, are less disturbed by the external environment, and are not affected by the external weather.

Main purpose: the anechoic chamber is used to simulate open field, at the same time to measure radiation radio disturbance (EMI) and radiation sensitivity (EMS). The size of the anechoic chamber and the selection of RF absorbing materials are mainly determined by the appearance size and test requirements of EUT, which are divided into 1m method, 3M method or 10m method. Our company can customize all kinds of anechoic chamber for customers to meet the needs of accurate test.
