Product Description

Outline

The QAM modulator is a high performance modulator developed according to DVB-C (EN300429) 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.
