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. The RF shielded room forms the basis for a semi-anechoic chamber. See references 2 and 3 for further details on how RF absorber materials work and for help in choosing the RF absorber material that best suits your needs. In contrast, the reflections that pass-through foam absorber material attenuate differently (sometimes none at all) depending of the angle of incidence of the RF field impinging upon it.Īlthough the floor is reflective, the remaining five sides of the chamber are treated with ferrite tile, RF foam absorber, or a hybrid combination of the two to make the chamber appear more like free-space to any RF energy produced within it. The reason the floor is kept reflective and not loaded with absorber is because it replicates the real world more closely to that of a free space environment and because radiated emissions measurements are more repeatable and accurate if the RF energy emanating from the equipment under test (EUT) is fully reflected. The term “semi” denotes that a portion of the chamber is reflective, usually the sheet metal ground reference plane located on the floor of the chamber. The term “anechoic” means non-reflective, non-echoing, and echo-free. These standards describe in great detail the methods of measurement of radio-noise emissions from low-voltage electrical and electronic equipment. Semi-anechoic chambers along with OATS are the preferred test facilities described in nearly all radiated and conducted emissions testing standards including ANSI C63.4 and CISPR 16. Out of all of the different types of EMC test facilities used to perform EMC testing, the most common one is undoubtedly the semi-anechoic chamber. There are many different types EMC test facilities, test cells, open area test sites (OATS) and EMC test chambers used for EMC testing. With its specific requirements for the test site, Frankonia’s FAC-3 is supremely prepared to meet our customers’ demands.An electromagnetic compatibility (EMC) or Electromagnetic Interference (EMI) chamber is a highly specialized piece of test equipment used in the testing of electronic devices against regulatory standards concerning both radiated and conducted radio frequency (RF) emissions and immunity. Without the reflections from the floor, a height scan is no longer necessary. It is designed as full compliant chamber for measurements under free-space conditions and is based on CISPR 16-1-4 as a test site without ground plane. The FAC-3 L is the extended version of Frankonia’s fully anechoic chamber solution at 3,0m measuring distance for EMC tests on table top positioned EUT’s as well as on floor-standing EUT’s.
