    • In a communications system including a base station coupled to a transmission antenna by means of a transmission feeder cable, and coupled to a receiving antenna by means of a receiving feeder cable, a method and system for testing the antennas and feeder cables includes a testing apparatus located at or near the antenna end of the feeder cables. A processor located within the testing apparatus initiates tests in response to commands received from the base station by means of a digital interface, which preferably uses one or both feeder cables as a communications medium. The testing apparatus includes directional couplers for each of the feeder cables, and corresponding power detectors for measuring both forward (incident) and reverse (reflected) power. All test results may be sent back to the base station, by means of the digital interface, for further analysis and status reporting.
    • 在包括通过传输馈电电缆耦合到发射天线的基站并且通过接收馈线电缆耦合到接收天线的基站的通信系统中,用于测试天线和馈电电缆的方法和系统包括测试装置 位于馈线电缆的天线端或其附近。 位于测试装置内的处理器通过数字接口响应于从基站接收的命令发起测试,数字接口优选地使用一个或两个馈线电缆作为通信介质。 测试装置包括用于每个馈电电缆的定向耦合器,以及用于测量正向(入射)和反向(反射)功率的相应功率检测器。 所有测试结果可以通过数字接口发送回基站进行进一步分析和状态报告。

The testing apparatus includes directional couplers for each of the feeder cables, and corresponding power detectors for measuring both forward (incident) and reverse (reflected) power. A test tone generator places a known signal on the receiving feeder cable to enable the receiving antenna VSWR to be measured, as well as to transmit the test tone down to the base station for use in measurement of receiving feeder cable attenuation. On the transmission side, incident power of a known signal supplied by the base station to the transmission feeder cable may be measured by the transmission power detector at the top of the transmission feeder cable. Measuring the amount of power reflected back by the transmission antenna then enables determination of the transmission antenna VSWR. All test results may be sent back to the base station, by means of the digital interface, for further analysis and status reporting.
