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.

TEST ITEM APPLICATION FREQUENCY RANGE
CE101 Hot, neutral, ground lead 120Hz-10kHz (powered on)
CE102 Hot, neutral, ground lead 10kHz-10MHz (powered on)
CS101 Hot lead 120Hz-150kHz (powered on)
CS114 AC cable (bundle, lead line) 10kHz-200MHz (powered on)
CS115 AC cable (bundle, lead line) 5A, 30n seconds
CS116 AC cable (bundle, lead line) 0.01, 0.1, 1, 10, 30, 100MHz (powered on, powered off)
RE101 Front, rear, left, right, top 30Hz-100kHz (powered on)
RE102 Front, rear, left, right, top 2MHz-18GHz (powered on)
RE101 Front, rear, left, right, top 30Hz-100kHz (powered on)
RE103 Front 2MHz-18GHz (powered on)
