摘要： A real time apparatus for testing a DTV antenna transmitting system, wherein the DTV antenna transmitting system transmits an original signal from a DTV transmitter to a DTV transmitting antenna, is disclosed that includes a probe, wherein the probe is connected in series with the DTV antenna transmitting system, and senses signals traversing the DTV antenna transmitting system. An error detector of the testing apparatus compares the received signal to the original signal to identify the magnitude and location of errors.

摘要： A monitoring system for an transmission line, such as a multi-channel television broadcasting antenna feed line, gathers data about the physical and electrical condition of the line in real time. The system can detect and localize deterioration and other time-dependent faults in the transmission line by the tendency of faults to produce reflections back to the transmitter that were not part of the original characterization of a particular installation. Some kinds of faults, identified early enough, can be corrected without replacing components, and especially without shutting down the transmission line during prime view hours. Other faults can be detected in time to order replacement parts before the underlying problem becomes severe, and to allow servicing during periods of low demand.
摘要翻译：用于诸如多声道电视广播天线馈线的传输线的监控系统实时收集关于线路的物理和电气条件的数据。系统可以通过故障产生反射回发射机而不是特定安装的原始特征的变化来检测和定位传输线路中的恶化和其他时间依赖的故障。一些早期发现的故障可以在不更换部件的情况下进行更正，特别是在黄金观察时段内不要关闭传输线。在潜在问题变得严重之前，可以及时检测到其他故障，以便订购更换部件，并在低需求期间进行维修。

摘要： A monitoring system for an RF transmission system, such as a multi-channel television broadcasting antenna feed system, gathers data about the physical and electrical condition of the RF transmission system in real time. The system can detect and localize deterioration and other time-dependent faults in the transmission system by the tendency of faults to produce reflections back to the transmitter that were not part of the original characterization of the installation. Some kinds of faults, identified early enough, can be corrected without replacing components, and especially without shutting down the transmission system during prime viewing hours in the case of television broadcasters, or during a critical period of use of the system in the case of other user types. Other faults can be detected in time to order replacement parts before the underlying problem becomes severe, and to allow servicing during periods of low demand.
