Instruction
RMT9020 DVB-T Modulator adopts several advanced functions and technologies, based on its fundamental module. It adopts Linear Digital Pre-Distortion and Non-Linear Digital Pre-Distortion, with which output performance of digital TV transmitters are effectively improved. The device supports all modes of DVB-T, either Single Frequency Network(SFN) or Multiple Frequency Network(MFN), with ability of hierarchical modulation. RMT9020 inputs with 4ASI and 1Tuner(for DPD), and additionally with 1GPS 10MHz reference clock and 1GPS 1PPS. It then modulate and output 1*Tuner in 30~960MHz, in good index. The device is widely used in countries and markets adopting DVB-T standard, offering a good choice for operators of digital TV broadcasting and head-end providers.
