Cofdm dvb-t rf modulator for terrestrial digital tv system



Outline

The COL5600 DVB-T modulator is a high performance modulator developed according to DVB-T (EN300744)  standard. It adopts advanced framing structure, channel coding and modulation technology. And it also supports both MFN(Multi-frequency network) and SFN (single frequency network). It has 2 AIS input ports,  one GPS.10MHZ input port  and one 1 PPS input port. In order to improve the output performance of the transmitter,the DVB-T modulator  can simultaneously support linear and nonlinear pre-correction. This device supports local and remote control  through NMS software.
