本标准描述了测量（1）条主线电缆和精密航空公司之间连接的单一主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 standard describes a procedure to measure the Return Loss characteristics of a single Mainline Pin Connector interfaced between (1) mainline 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.
