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.FeaturesFully complying with DVB-T standard (EN300744)Both SFN and MFN supportTransfer mode 2k, 4k, 8k optionalHierarchy modulation Alpha1, 2 and 4 optionalTransfer bandwidth 6M, 7M and 8M optionalSupporting linear and non-linear correctionExcellent phase noise and MER performance, MER≥40dbRF output range 110~860MHz, 1hz stepTwo ASI inputs supporting hot backupConstant temperature crystal oscillator, frequency stability is high up to 0.1ppmFull-size front panel LCD display and keyboard, NMS management.SpecificationsInput2 channels ASI input,hot backup, BNC portGPS 10Mhz reference clock input, BNC portGPS 1PPS input, BNC portModulationstandardEN304 744FFT2K,4K,8Kbandwidth6M,7M,8MconstellationQPSK,16QAM,64QAMGuard interval1/4,1/8,1/16,1/32FEC1/2,2/3,3/4,5/6,7/8Hierarchy modulationAlpha=1,2,4RF outputASI loop out2channels ASI loop out, BNC portinterfaceN type, 50ΩimpedanceRF range110~860MHz,1hz stepATT-16dbm~0dbm,0.5db stepMER≥40dbLinear pre-correctionCorrection points16Non-linear pre-correctionCorrection points256SystemFull-size front panel LCD display and keyboard, NMS managementSoftware upgradingGeneralDemission (W*L*H)482mm×455mm×44.5mmWeight4.9kgTemperature0~45°C(operation),-20~80°C(storage)Power supplyAC 110V±10%,50/60Hz or AC 220V±10%,50/60HzConsumption28.6W
