Dexin NDS3343B digital satellite receiver with mux-scr and qam modulator
Outline
NDS3343B is a high performance and cost-effective mux-scrambling QAM modulator designed by Dexin. It adopts inner drawer-type structural design which greatly facilitates the change of modules (4 Tuner/4ASI) as needed. To meet customers’ various requirements, this device is also equipped with 1 ASI in, 1 RF in, 1RF out and 2 ASI out port. After 4 channels multiplexing, scrambling and QAM modulating process, then it gives 4 RF output (4 adjacent frequencies).
The device is characterized with high integrated level, high performance and low cost. This is very adapting to newly generation CATV broadcasting system.
