Detection apparatus for cable assembly radio-frequency leakage and detection method

Abstract

The invention discloses test equipment and a test method to leak of RF cable assemblies. Microwave test signals are sent to measured cable assemblies from the RF signal source, and signals are absorbed by matched load through cable assemblies. Microwave pathway is constituted of RF signal generator, cable assemblies, matched load. There is microwave signal leakage existing around the object when the signal goes through the objects. These signals are collected by signals collection device and sent into microwave receiver. We can get the decibel value of the corresponding pieces of RF leakage through the readings letters of RF signal source and microwave receiver.

Description

technical field [0001] The invention relates to a testing technology for radio frequency leakage of a cable assembly, in particular to a testing device and a testing method for a radio frequency leakage of a cable assembly. Background technique [0002] Like connectors, users place requirements on RF leakage (shielding efficiency) for cable assemblies. Due to the complexity of the structure of the cable assembly, there are not only various types of connectors, but also different types of cables, and there are cable assemblies of different lengths. Therefore, it is relatively difficult to perform RF leakage testing on cable assemblies. The cable assembly is actually a coaxial transmission line, so the definition of its radio frequency leakage (shielding efficiency) is equivalent to that of the transmission line. The so-called radio frequency leakage (shielding efficiency) of the cable assembly is the ability of its outer conductor to protect the transmission line from exter...
