Abstract: A high-speed high-voltage pulser especially designed to operate in high radiation environments. The pulser uses a primary side driver and switches in front of an isolation gate transformer. The primary side driver and switches provide amplified and fast complementary pulse signals to the transformer. The transformer has top and bottom secondary windings, which respectively receive the complementary signals, and deliver them to secondary side drivers and switches. The switches are implemented with series-connected FETs.

Abstract: A test fixture for testing the operation of a device having components installed at a first location. The components are connected to associated apparatus installed at a separate second location, and the components collectively have electrical inputs and outputs connected to a control at the second location. The test fixture has a housing and a plurality of output conductors at the first location. First ends of selected ones of the plurality of output conductors are connectable to selected ones of the inputs and outputs of the components. A power supply and a plurality of switches are mounted to the housing. Each of the plurality of switches has one contact connected to the power supply and another contact connected to a second end of respective one of the plurality of output conductors, whereby actuating one of the switches causes a respective one of the components to operate.
