Low insertion loss and high isolation.
The channel status display
Integrated microprocessor, working parameters and fault information of the equipment through the centralized monitoring unit is shown in Chinese color display, also can through the RJ45 network management interface system platform to realize the centralized monitoring network.
The RF switch module is mainly used in the headend room of CATV HFC network. Users can set the switching conditions to achieve the main and preparation RF signal channel switching freely. Can automatic switch to the channel with more better signal quickly to ensure the quality of the CATV signals and improve the safety and reliability of the whole network.
The RF signal in the main and preparation channel is amplified by the splitter and amplifier tube, then through the RF detector tube detection into voltage into the microprocessor to realize the monitoring the input RF signal of the two channels. The main road detection voltage RF detector tube at the same time by high isolation unit circuit processing input to the display, the operation unit comparator circuit after treatment respectively drives the status indicator light emitting diode and RF relay. The RF signal when no input RF signal or the main road is lower than the input RF switch calibration value, the device is switched to the preparation work, indicating the state of light emitting diode signal is given.
