FLEXMod 211

DVB-S Modulator with embedded Remultiplexer

Integrated solution for the distribution/regeneration of DVB-S services. The system is composed by a demultiplexer/multiplexer and a DVB-S modulator with RF output. Easily configurable through a UART serial port, allows the development of a complete and very compact modulation system.
