The Basics of EMC Testing for Electronic Devices

Electromagnetic and radio frequency interference shielding is concerned with the “noise” and electromagnetic emissions from signals and currents inside electronic devices. Electronic devices can impact how nearby devices function and they can be susceptible to emissions from other neighboring devices.

The effects of interference range from annoying (e.g. static on the radio) to life-threatening (e.g. malfunctioning aircraft controls or electronic breaking signals).
