EMI and EMC Testing

Unwanted electromagnetic energy can disrupt the operation of electronic devices, such as computers. To prevent such disruptions and ensure compatibility between devices operating in the same vicinity, Panasonic Toughbook mobile computers are designed to comply with MIL-STD-461F for both, electromagnetic emission and susceptibility. This standard establishes requirements for the control of electromagnetic interference (EMI) and electromagnetic compatibility (EMC) of electronic, electrical and electromechanical equipment and subsystems for use by the Department of Defense.

Because electromagnetic radiation crosses many frequency ranges and can affect multiple applications, Panasonic and third-party testing is conducted on fully-rugged Toughbook mobile computer models to verify EMI and EMC compliance across a wide range of samples. Ten different tests, listed below, are conducted on Toughbook fully-rugged computers to comply with MIL-STD-461F electromagnetic tolerances when operating in their intended environment.
