14KHz-40GHz more than 100dB for emc RF shielding testing chamber
RF noise free environments and RF noise containment are important for many applications including EMC / EMI testing, security, safety and regulatory compliance. With thousands of shielded rooms and anechoic chambers supplied globally to hospitals, government agencies, data centers, test labs and private organizations, you can be sure that we have the expertise and capabilities required.
When a shielded room is necessary?
· If your lab is near a broad spectrum emitter (i.e equipment that transmits multiple frequencies under 400Hz), radio tower, mobile phone transmitter or other large field generators, then you should consider a shielded room.
· If your research is in the gamma band and you do not want to use a 60/50Hz notch filter to remove mains power noise, you might consider a shielded room. We recommend taking the steps above to first minimize the mains power noise. If that is not sufficient for your needs, then a shielded room may help.
