EMI Testing and EMC Testing

Sigma is an ISO 9001:2008 accredited testing laboratory which provides solutions for EMI/EMC testing for Electrical and Electronic appliances, medical equipment , automobile and aeronautical engines, marine gear noise emissions, self-generated RF transmissions from antennas, and more.The product that meant to be used for industrial, residential, commercial and military purposes are subjected to be tested on various parameters that made them perform well in electromagnetic environment. These products are tested through EMI/EMC testing.

The EMC or Electromagnetic Compatibility Testing requires appropriate electrical and structural design, equipment installation, wiring installation, and equipment qualification.

The EMI or Electromagnetic Interference Testing is performed to ensure that your product will perform properly when subjected to the electromagnetic environment in which it is expected to operate.

Federal Communications Commission(FCC)
FCC stands for Federal Communications Commission. It is an agency of the U.S. Federal Government which is responsible for the management of the radio spectrum in the US. The FCC protects against "radio and broadcast pollution", both by enforcing standards of broadcast decency, and by regulating Electromagnetic noise sources.

Electrical and electronic products may interfere by producing radio spectrum noise. As electric current moves around inside an electrical product, the current will produce electromagnetic field waves that will travel through space. Those waves may affect other electrical currents in other products, and cause unwanted interference.

The FCC has four main categories of equipment authorization:

Different authorization is needed for different types of equipment. Technical expertise is needed to evaluate the design to ensure correct authorization.
