Outline
The COL5600 DVB-T modulatoris 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.
