Cable and Antenna Analyzer TW3300
Frequency Domain Reflectometer (FDR) is similar to Time Domain Reflectometer (TDR) in the name, and both are used for measurement of transmission line. TDR sends excitation signal of DC pulse which can be used to measure the On/Off and off position of a cable but is insensitive to RF problems that may result in fault and performance degradation of RF communication equipment. While FDR adopts sweep signal for measurement, by getting time domain specification through complex mathematical operation, it may detect sight performance degradation of RF in system so as to do timely maintenance, thereby saving high maintenance cost of damage due to delayed repair of RF cable
