Antenna test anechoic chamber with RF absorber
RF shielded room
The RF shielded room forms the basis for a semi-anechoic chamber. It’s a near RF-impenetrable metal box, that offers electric and magnetic field shielding effectiveness up to 100 dB over a wide range of frequencies. It’s good for emissions testing because no signals or ambient noise from the outside world can penetrate it, making it much easier to measure the emissions generated only by the EUT. It’s also good for immunity testing because no signals generated inside the enclosure can escape to the outside world, possibly causing harmful interference to equipment or personnel located nearby.
Keep in mind there are different types of shielding materials and configurations for semi-anechoic chambers and each of them have different shielding performance levels. If your application requires maximum shielding effectiveness, then you may want to consider shielding material that is double electrically isolated. This shielding has two layers of metal (one on the inner surface and one on the outer surface), typically connected at only the main grounding point of the chamber. If anything needs to be mounted to either the inside or outside of the chamber then the mounting screws selected should be keep short enough to penetrate just the first shielding layer and not go through the second.
Anechoic Chamber

Anechoic Chamber Description we provide Semi-EMC Chamber and Full EMC Chamber for EMC Testing.
An Anechoic Chamber generally consists of an RF shielded room which is either partially or fully lined with RF absorber material. It is used to perform several types of testing and measurements.
our chambers are typically constructed from the modular shielding system.
EMC anechoic test chambers are used by industry to perform radiated emissions and radiated immunity testing of electrical/electronic equipment to various International specifications such as EN 50147 part 2 / ANSI C63.4 / EN55022 / EN61000-4-3 and various CISPR documents.
Chambers are also designed for EMC testing for testing in accordance with military and avionics specifications such as MIL STD 4612E, DO 160 and DEF STD 59-41.
we offers a fully range of anechoic chambers, including:
