Anechoic Chambers

Full Anechoic Chambers aim to absorb energy in all directions. Semi anechoic chambers have a solid floor that acts as a work surface for supporting heavy items, such as cars, washing machines, or industrial machinery, rather than the mesh floor grille over absorbent tiles found in full anechoic chambers. The floor is damped and floating on absorbent buffers to isolate it from outside vibration or electromagnetic signals.

 What is Radiated Emissions EMC Testing?

Radiated emissions testing, involves measuring the electromagnetic field strength of the emissions that are unintentionally generated by your product. Emissions are inherent to the switching voltages and currents within any digital circuit, the only question is: how large are the emissions and do they comply with the emissions limits?

What Is Conducted Emissions Testing

Your device creates electromagnetic energy and a certain portion of it will be conducted onto the power supply cord. In order to restrict the amount of interference your device can couple back onto a power supply, it is necessary to measure these emissions (usually from 150 kHz – 30 MHz, and verify that they comply with specified limits. This helps to ensure that the local power supply remains relatively ‘clean’ and nearby devices won’t be affected by your device.
