Shielding Effectiveness test setup (SE)
MIL-STD-188-125 SE, CWI

The purpose of the Shielding Effectiveness (SE) test is to demonstrate the compliance of a facility and apertures POE with the shielding performance required.

Continuous Wave immersion test setup (CWI)

MIL-STD-188-125 CWI

Verification of small and mobile facilities is usually performed with the exposure of the system to a threat level EMP using a pulse simulator as presented here. But the verification of large or fixed facilities can only be performed with a low level illumination field in the frequency domain. It involves measuring the residual fields, charge/current densities and currents inside the facility while sweeping in the frequency domain on the whole EMP spectrum. It is then possible to assess the expected internal residual electromagnetic pulse due to the exposure to EMP by means of fast Fourrier transform and extrapolation.
