The Electromagnetic Interference (EMI) Laboratory offers several Electromagnetic Compatibility (EMC) services like EMC hardware design to meet the desired requirement, specification comparisons, consultation during design development, and prefabrication analyses. The EMI Lab provides intermediate testing as the design progresses, testing for shielding effectiveness, filtering, and grounding, final qualification testing of experiments in flight configuration, and testing at customer locations for items too large to fit in the EMI Laboratory shielded room.
This facility consists of three shielded rooms, two test chambers, and a control room. All walls, ceiling, and floors are constructed of 26-gauge galvanized steel sheets laminated to both sides of a structure core.
The rooms meet the electromagnetic wave attenuation requirements used by the National Security Agency (NSA). They prevent transmission of electromagnetic waves into, or out of, the enclosure, which provides low electric and magnetic field ambient conditions. Electrical power is provided through filtered AC lines to eliminate transfer of interfering signals such as radio, TV, and RADAR.
The large shielded enclosure is a fully functional package with support for stirred and tuned mode operation with Statistical Mode Averaged Reverberation test. This methodology of test is good for Immunity test or Shielding Effectiveness test.
