Wall Penetration in Shielded Rooms

Most RF companies have a shielded room (or “screen room”) for testing of sensitive circuits and equipment. In theory, the room takes advantage of Gauss’ Law to keep out interfering noise and signals. However, power, ventilation and other utilities must be available, as well as signal lines connected to equipment located outside the room. Those penetrations of the shielded space must not allow unwanted energy into (or out of) of the room.
