Modulator CDH9000-SCQM48

CDH9000-SCQM48, 48 in 1 IP QAM modulator is the latest generational Mux-scrambling-modulating all-in-one device developed by us. It has 48 multiplexing channels, 48 scrambling channels and 48 QAM (DVB-C) modulating channels, and supports maximum 512 IP input through the GE port and 16 non-adjacent carriers (50MHz~960MHz) output through the RF output interface. The device is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation CATV broadcasting system.
