Outline

 

The COL5400A QAM modulator is a high performance modulator developed according to DVB-C standard. It can receive various TS come from encoder, multiplexer, DVB gateway, scrambler and video server, and then disposes the TS by RS encoding, interleaving and QAM modulating. This device also has RF output and real-time monitoring function.
