Computer-controlled RS-105 test system for 1-M EUTS

Test procedure RS-105, within MIL-STD-461F, prescribes the use of a transverse electromagnetic (TEM) cell, or parallel plate transmission line to test equipment and subsystem enclosures against a non-classified form of the E1 nuclear electromagnetic pulse (NEMP) waveform [2]. A system is described which is capable of exposing a 1-meter cubed piece of equipment under test (EUT) to the 50 kV/m double-exponential waveform outlined in the standard. A Marx generator and peaking circuit are used to drive a TEM structure which has been optimized for performance in the metrics of waveform fidelity, mechanical strength, and reduced cost. The computer control, data acquisition, and reporting system are also discussed.
