Anechoic chamber

Anechoic chamber

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.

all-anechoic chamber reduces the interference of external electromagnetic wave signals to test signals, and the electromagnetic wave absorbing material can reduce the multipath effect caused by the reflection of walls and ceilings. It is suitable for emission, sensitivity and immunity experiments. Free space can be simulated in full anechoic chamber. Compared with the other two test sites, the floor, ceiling and wall of the anechoic chamber have the least reflection, the least interference from the external environment, and are not affected by the external weather.

Main uses: Anechoic chamber is used to simulate open field, and to measure radiation radio disturbance (EMI) and radiation sensitivity (EMS). The size of anechoic chamber and the selection of radio frequency absorbing materials are mainly determined by the size and test requirements of the tested equipment (EUT). It can be divided into 1 m method, 3 m method or 10 m method. Our company can customize all kinds of anechoic chambers for customers to meet the needs of accurate testing.
