IP Qam Digital Modulator
Product introduction
1. Outline
SFT3316 16-in-1 IP QAM modulator is the latest generational Mux-scrambling modulating all-in-one device developed by SOFTEL. It has 16 multiplexing channels, 16 scrambling channels and 16 QAM (DVB-C) modulating channels, and supports a maximum of 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 the newly generation CATV broadcasting system.
2. Key features
