Claim:
1. An apparatus for determining axial spacing between slip rings for impedance matching high-frequency signals through a slip ring assembly, the apparatus comprising: a signal generator that generates an incident signal; a shaft having a plurality of concentrically aligned conductive rings axially spaced along the shaft, wherein the plurality of conductive rings comprises a first conductive ring axially spaced at a first axial distance from a second conductive ring, wherein the shaft and the plurality of conductive rings are submerged in a bath of a liquid or encased in an epoxy; a first twisted wire pair electronically coupled at one end to the signal generator and electronically coupled at a second end to inputs of the first and second conductive rings; and a second twisted wire pair electronically coupled at one end to outputs of the first and second conductive rings.
