Instruction

RMT9220 DVB-T2 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/T2, either Single Frequency Network(SFN) or Multiple Frequency Network(MFN), with ability of hierarchical modulation. RMT9220 inputs with 1*ASI, 1*IP and 1*Tuner(for DPD), and additionally with 1*GPS 10MHz reference clock and 1*GPS 1PPS. It then modulate and output 1*Tuner in 30~999MHz, in good index. The device is widely used in countries and markets adopting DVB-T/T2 standard, offering a good choice for operators of digital TV broadcasting and head-end providers.
