Electromagnetic Pulse/Transient Threat Testing of Protection Devices for Amateur/Military Affiliate Radio System Equipment. Volume 3. Test Data, Electromagnetic Pulse Testing of Protection Devices. Section 1. High Energy Pulse-Device Failure Test. 50 Ohms Impedance 25,000 Volts-4000 Amps, 100 Joules.

This technical report discusses the vulnerability of equipment used by amateurMARS radio operators in the United States to disruption or damage by transient electromagnetic effects such as lightning, voltage surges, and electromagnetic pulse EMP waves. It also reports the results of two test programs one to evaluate existing transient suppression devices and components, and one to evaluate the response of amateur radio equipment to an EMP transient environment. Based on the test results, the report recommends procedures and a low-cost installation scheme which will significantly increase the operational survivability of amateur type communications equipment in a lightning or EMP environment. This report consists of three volumes. Volume III 1298 pages contains the raw test data in the form of oscilloscope photographs attached to the test data in the form of oscilloscope photographs attached to the test data sheets for both test programs, as well as, written test descriptions and bench check measurements from the equipment test program. For most purposes Volume I should provide sufficient information. Volume II would be required to obtain more detailed descriptions of the the test programs and tested devices and equipment. Volume III would only be required if a separate analysis of the test data is being made. Keywords include Amateur Radio Equipment EMP, Lightning Protection Electromagnetic Pulse EMP Protection Devices Test EMP Lightning and Transient ElectricalMagnetic Pulses.
