If an rf adapter or a cable assembly is evaluated by the rf testing and measurement perspective, the engineer is not only concerned with the target at the time of delivery, but also is more concerned with its service life.
The life of the rf cable assembly depends on three factors: the bending resistance of the cable ; Good connections between cables and connectors and their anti-bending properties; Connector’s service life. For the first two factors, the jig or specification operator action can be taken to ensure that for the life of the connector: for the connector’s life, can only rely on the quality of the connector itself and the assembly process.
In normal condition, the life of the rf connector will be well over 500 times standard. The insertion loss of rf connector increases gradually with mechanical wear. However, the VSWR has hardly changed. If there is no obvious fault of the cable, the compulsory scrapping system should be established to guarantee the test index.
