Product Overview
NDS3308T 8in1/16in1/24in1/28in1/32in1 DVB-T modulator is an all-in-one device developed by DEXIN. It supports maximum 256 (or 1024) IP input through the GE/SFP port and has 8 (or 16/20/24/28/32) multiplexing channels and 8 (or 16/20/24/28/32) DVB-T modulating channels of non-adjacent carriers (50MHz~960MHz). The device is characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system.
