Overview
The IEC 63137-1:2019 standard, published by the International Electrotechnical Commission (IEC), provides the generic specification for standard test radio-frequency (RF) connectors-specifically grade 0 connectors. This standard outlines the general requirements and test methods crucial to ensuring performance, reliability, and quality of RF connectors used in measurement applications.
Primarily, these grade 0 standard test RF connectors serve as precise adapters designed to test grade 1 and grade 2 RF connectors. One end of the connector typically features a precision connector interface compatible with high-accuracy measurement equipment, while the other end connects to the connector under test. By adhering to IEC 63137-1:2019, manufacturers and testing laboratories ensure consistent electrical performance verification throughout the RF connector supply chain and testing processes.
