8 demodulator/ 8 Multiplexer/8 Scrambler/8 Modulator Headend Digital TV Platform

详情

JXDH****3 RF all in one Mutiplexers/Scramblers/QAM Modulators is new generation QAM modulator, This equipment use modular design, each modular is separate working, each module can receive the satellite digital /Cable digital / ground digital signal though RF port, module integrated 8 demodulator, 8 sets Muliplexer, 8 sets standard scrambler and 8 sets DVB-C QAM modulator, use 1 RF port to output *8MHz~**0MHz 8 sets adjacent frequencies, 

Ds. I U standard case Max support 1 module (8 frequencies ), can be any combine the case, meet the required frequencies quantity. 

This equipment is highly assembled, high performance with low cost, quite suitable for new generation CATV system, can be used in main headends and branch headen
