MDDT01 DVB-T Modulator is a high performance modulator developed according to DVB-T (EN300744) standard. It has4 AIS input ports, one GPS 10MHZ input port and one 1 PPS input port, supporting both MFN (Multi-frequency network) and SFN (single frequency network). In order to improve the output performance of the transmitter, this DVB-T modulator is able to support adaptive linear and nonlinear digital pre-distortion. This equipment supports local and remote control through NMS software. It can be widely applied in DVB-T digital broadcasting system.
