8*DVB-S/S2 to qam 4 in 1 dvb-c rf modulator

Outline

COL 5441BT QAM Modulator with MUX &SCR (8 tuner) is a high performance and cost-effective tuner  mux-scrambling QAM modulating device latest designed by our Company, Which provide 8 DVB-S2 tuner input  interface. After 4 channels multiplexing, scrambling and QAM modulating process, then it gives 4 RF output  (4 adjacent frequencies by 1 RF port). The device is characterized with high integrated level, high performance  and low cost. This is very adapting to newly generation CATV broadcasting system.
