VNA test cable assembly is a high-performance phase stable test cable mainly utilized in vector network analyzers. It supports continually and frequently repeated bending. Hence it can be applied to high precision microwave electrical parameter testing under environments such as laboratory, production line, testing system etc. From DC to 67GHz, it provides extremely stable VSWR and insertion loss, extraordinary mechanic phase & amplitude stability and repeatedly connection Additionally, high-precision NMD/APC connector in solid and light mechanical structure withstands bending, squeezing, twisting, stretching and other external forces while maintaining reliable performance. Dressing up with our special stainless steel double spiral strip+black nylon armor, the assembly can effectively extend the service life of the vector network analyzers.


 Extremely accurate measurement with stable electrical performance up to 67GHz

 Same excellent phase & amplitude stability even at flexure

 Super robust cable, equipped with NMD connector, can withstand repeated mating, extrusion, twisting and bending, extraordinary reliability

 Extend the validity of utilization after calibration, reduce the repeated calibrations
