Product Description

Outline

STM-1350 4 in 1 mux-scrambling QAM Modulator is a high performance and cost-effective ASI mux-scrambling QAM modulating device latest designed by Dexin Company. It provides 16 ASI input interface. After 4 channels multiplexing, scrambling and QAM modulating process, then it gives 4 RF output (4 adjacent frequencies by 1 RF port) and gigabit IP output. The device is characterized with high integrated level, high performance and low cost. This is very adapting to newly generation CATV broadcasting system.



Features

*Simultaneously support 4 simulcrypt CA

*Support accurate PCR adjusting

*Support PSI/SI editing and inserting

*Excellent RF output performance index, MER≥40db

*Support LCD display and keyboard

*Support SNMP management
