16 Channel QAM Multiplexing and Scrambling IP Modulator
Product Overview
QAM16 16 in 1 IP QAM modulator is the latest generational Mux-scrambling-modulating all-in-one device developed by GHCOMTEK. It has 16 multiplexing channels, 16 scrambling channels and 16 QAM (DVB-C) modulating channels, and supports maximum 512 IP input through the 3 GE ports 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.
