Abstract
A test architecture performs calibration and site verification testing of the effectiveness of a radiation shielding structure within which electronic equipment is housed. An external subsystem is outside a shielding cabinet, and an internal subsystem resides with the electronic equipment within the shielded equipment housing proper. The external subsystem includes a host computer, which controls the operation of transmit and receive subsystems. An external receiver is selectively coupled by the host processor to either an RF receive antenna or to a current sense probe. All control signals from the external subsystem are conveyed into the shielded cabinet by way of fiber optic links, in order to preserve the shielding effectiveness of the cabinet. Having the source of test signals and its associated transmission antenna located within the shielded cabinet serves to minimize the impact of such signals on circuits within the environment outside the cabinet.
