Product Description
Discription
The 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.
