8*DVB-S/S2 to 4×QAM modulator with multiplexer-scrambler

Overview

DVB-S2 to 4×QAM Trans-modulator support 6/8*DVB-S/S2 (QPSK/8PSK) transponders and 6/4/3*ASI input multiplex, and scramble 4*MPTS to output selected programs through 4×QAM RF channels. It provides a cost-effective and stable solution for TV operators to re-distribute programs via HFC network. It suits 1U rack and can be configured by front panel LCD and NMS (network management software).
