Abstract

The incorporation of fiber optic signal transmission into a high voltage spark discharge experiment to reduce radio-frequency interference is described. Electrical isolation and the elimination of ground loops provided by the fiber optic links allow the use of sensitive CMOS computer logic in control of an electrically noisy spark source experiment. Circuit schematics are given and performance with three optical fiber cable types is described.
