The impedance probe is a measurement device to measure plasma parameter likeelectron density. It consists of one electrode connected to a network analyzervia a coaxial cable and is immersed into a plasma. A bias potential superposedwith an alternating potential is applied to the electrode and the response ofthe plasma is measured. Its dynamical interaction with the plasma inelectrostatic, kinetic description can be modeled in an abstract notation basedon functional analytic methods. These methods provide the opportunity to derivea general solution, which is given as the response function of the probe-plasmasystem. It is defined by the matrix elements of the resolvent of an appropriatedynamical operator. Based on the general solution a residual damping forvanishing pressure can be predicted and can only be explained by kineticeffects. Within this manuscript an explicit response function of the sphericalimpedance probe is derived. Therefore, the resolvent is determined by itsalgebraic representation based on an expansion in orthogonal basis functions.This allows to compute an approximated response function and its correspondingspectra. These spectra show additional damping due to kinetic effects and arein good agreement with former kinetically determined spectra.
