Telecast MDDT01A 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 4 ASI 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. 


Fully complying with DVB-T standard (EN300744) SFN and MFN supporting Transfer mode 2k, 4k, 8k optional Hierarchy modulation Alpha1, 2 and 4 optional  Transfer bandwidth 6M, 7M and 8M optional Supporting linear and non-linear correction Excellent phase noise and MER performance, MER ≥42db RF output range 36~960MHz, 1hz step Four ASI inputs supporting hot backup Constant temperature crystal oscillator, frequency stability is high up to 0.1ppm Full-size front panel LCD display and keyboard, NMS management.
