Modulator CDH9000-SCQM32 QAM 32 Frequencies with IP Scrambler & PSI Editor

CDH9000-SCQM32, 32 in 1 IP QAM modulator is the latest generational Mux-scrambling-modulating all-in-one device developed by us. It has 32 multiplexing channels, 32 scrambling channels and 16 QAM (DVB-C) modulating channels, and supports maximum 512 IP input through the GE port and 32 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.
