Testing

EMC stands for electromagnetic compatibility chamber and is specially designed to create an enclosure with an extremely high level of shielding against electromagnetic intrusion. The chamber is a specialized kind of test equipment used when testing electronic devices. All devices developed and produced by Hectronic must meet and uphold the required standards concerning both radiated and conducted radio frequency emissions and immunity.

No matter how loud you scream inside an EMC chamber, there won’t be any echo. The sound won’t bounce of the walls and it’s the same principle when it comes to radiation inside the chamber. Everything is concealed inside the chamber. EMC chambers are also called anechoic chambers, and the word anechoic simply means “without echo”. The walls, floor and ceiling are all lined with radiation absorbent material that is designed to absorb all sound and radio waves and therefore eliminating all reflection.

By shielding a device against all outside interference, you can accurately measure the strength of the electromagnetic field that is generated by the device under test. The chamber will give us advantage and Hectronics engineers are now able test the radiated emission or radiated immunity of a device in our lab in Uppsala, during the development process. Depending on what field of industry a device will be operating in, there are different industry standards that determines emission and immunity limits. But there are more applications for an EMC chamber other than radiation testing. You can also test wireless transmitters, antennas, and specific absorption rates.

By being able to do the pre-compliance testing in our lab, we can both shorten the time to market and ensure that the device will pass the final compliance testing.
