Abstract
Abstract A coaxial coupling for connecting a test or other incidental signal with a waveguide by means of a probe within the guide is provided with a cavity forming cap so that when the connection is not in use and the cap is in place, the cap together with the probe forms a quarter wavelength shorted stub which renders the probe electrically invisible within the waveguide.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A signal connection comprising a conductively bounded waveguide for electromagnetic wave energy, a coaxial cable connector having center and outer conductors affixed to the boundary of said guide and adapted to receive a mating connection of a coaxial cable, a conductive probe extending to an end within said guide from said center conductor, means for disabling and rendering electrically inactive said coaxial cable connector comprising a shorted coaxial structure adapted to be interchangeable with said mating connection on said connector and for forming with said connector a shorted coaxial cavity, said shorted coaxial cavity having an outer boundary and a center conductive member and a shorting boundary therebetween, said outer boundary being adapted to be removably affixed to the outer conductor of said connector so that the center member of said cavity contacts the center conductor of said connector, said cavity having such dimensions that the electrical distance from said shorting boundary to said end is an odd multiple of onequarter wavelengths.
Claim 2
Dependent Claim
162 words
A signal connection comprising a conductively bounded waveguide for electromagnetic wave energy, a coaxial cable connector having center and outer conductors affixed to the boundary of said guide and adapted to receive a mating connection of a coaxial cable, a conductive probe extending to an end within said guide from said center conductor, means for disabling and rendering electrically inactive said coaxial cable connector comprising a shorted coaxial structure adapted to be interchangeable with said mating connection on said connector and for forming with said connector a shorted coaxial cavity, said shorted coaxial cavity having an outer boundary and a center conductive member and a shorting boundary therebetween, said outer boundary being adapted to be removably affixed to the outer conductor of said connector so that the center member of said cavity contacts the center conductor of said connector, said cavity having such dimensions that the electrical distance from said shorting boundary to said end is an odd multiple of onequarter wavelengths.
Claim 3
Dependent Claim
26 words
The connection according to claim 1 wherein said center member of said cavity slidably engages said center conductor of said connector for relative axial movement therebetween.
Claim 4
Dependent Claim
26 words
The connection according to claim 2 including an impedance discontinuity means associated with said slidable engagement for varying said electrical distance with said relative axial movement.
