About the QC Interface

Quick-Change RF adapters are designed for use with high power testing and monitoring equipment used across a broad variety of commercial applications. The quick-change adapter interface (referred to as the “QC” end) allows two connectors to be quickly mounted onto a common interlink housing in any standard interface combination to match your test equipment and DUT. The common QC interface at the interlink housing ensures consistency of results. Quick-Change adapters represent a quick and easy way to match your tester and equipment without performance degrading adapters.
