32 Channel QAM Multiplexing and Scrambling IP Modulator
Description:
NDS3332 32 in 1 IP QAM modulator is Mux-scrambling-modulating all-in-one device. It supports maximum 1024 IP input through the 3 GE ports and 32 multiplexing scrambling QAM (DVB-C) modulating channels with non-adjacent carriers (50MHz~960MHz) output through the RF output interface. Its pay-as-you-grow modular design and flexible configuration are making it extremely scalable, very reliable with high performance, all of which are adaptable to newly generation CATV broadcasting system
