Abstract:
A Probe tip structure for connection to an end of a coaxial transmission line having an inner electrical conductor surrounded by an outer electrically conducting shield, said probe tip structure consisting of a solid piece of electrically conducting material having a bore therein at one end thereof, said bore is symmetrical about its axis, and further having at least one electrically contacting member at another end thereof and machined therefrom, said contacting member itself having an end adapted for making contact to a circuit to be tested, said bore extending farther into said probe tip with a smaller size which is also symmetrical about its axis adapted to receive said inner conductor therein said inner conductor also having an end adapted for making contact to said circuit to be tested, a spacing between said contacting member and said inner conductor is chosen to control the impedance of said probe tip structure.
