Determination of Responses of Protected and Unprotected Electric Initiators to Electrical Stimuli. A Franklin Institute 34.5 cm Ferrite Attenuator

摘要

A single sample of the Franklin Institute 34.5 cm. ferrite attenuator was evaluated by Genistron over the frequency range from 100 cps to 10 gc. The unit was packaged as a protective device and tested to determine RF operating characteristics. Quantities measured directly were input impedance, load impedance of the connected inert MK-1 squib, transfer impedance and/or voltage attenuation = 20 log Vsubi/Vsubp. These data were used to compute the evaluation parameters Power Attenuation and minimum possible Insertion Loss, which are presented in graphic form. The measured time delay of 22 microseconds is also shown in an oscilloscope photograph. (Author)
