本文件描述了测量连接在硬线电缆和精密航空公司之间的单硬线引脚连接器的回波损耗特性的程序。它实现了网络分析仪的时域选通功能，可以移除接口，并从DUT（被测设备）测量中终止远端。

This document describes a procedure to measure the return loss characteristics of a single hard line pin Connector interfaced between hard line cable and a precision airline. It implements the time domain-gating features of the network analyzers, which removes the interfaces, and far end termination from the DUT (device under test) measurement.
