ABSTRACT:
The tester includes a test cabinet which forms an electromagnetic shield enclosure with an aperture in the top wall through which a device under test extends and a thermal hood intersecting the top wall to form a thermal and electromagnetic shield enclosure about the device under test. A device under test receptacle is mounted to a removable electromagnetic shield load board with coaxial connectors which snap into coaxial connectors on a electromagnetic shield mother board which is permanently mounted in the electromagnetic shielded enclosure. The connection of the terminals at the bottom of the mother board are by matched impedance, equal length coaxial cables to the A.C. interface and a ribbon cord to the D.C. interface. The environmental enclosure, the housing are grounded to frame ground and the load board and the mother board are all grounded to instrument ground which is then attached to frame ground via single ground point.
