Magnetic Probes and the Instrumentation of Capacitive Discharges

摘要

Equations have been derived for the output signal (V sub s) of an inductive probe excited by the capacitive discharge of a series RLC circuit. These equations are applicable to both the strongly coupled and the weakly coupled probe and can be used to obtain design criteria or to correctly interpret a measured output signal. Quite generally the equations show that the magnitude and time dependence of (V sub s) are not related to those of the discharge current by Mdi/dt unless certain inequalities exist between the three parameters alpha, beta and gamma.
