Patent ID: 6863564

Claim:
A testing system comprising: a network analyzer having a radio frequency out port and a radio frequency in port; a first coaxial cable having a first end electrically coupled to the second end of the first coaxial cable and a second end; a radio frequency test probe having a first end electrically couple to the second end of the first coaxial cable and a second end; an adapter having a first end in contact with the second end of the radio frequency test probe and a second end, the adapter including a ground sleeve having a first ground sleeve end adapted to contact a ground lead of a coaxial cable, a second ground sleeve end adapted to contact a ground probe of the test probe, a signal pin positioned inside of and spaced apart from the ground sleeve, the signal pin having a first signal pin end adapted to contact a signal lead of a coaxial cable and a second signal pin end adapted to contact a signal probe of the test probe; and a second coaxial cable having a first end connected to the second end of the adapter and a second end in communication with the radio frequency out port; wherein the first coaxial cable, the radio frequency test probe, the adapter, and the second coaxial cable all have the same impedance.
