Features Specifications » DVB T Exciter (Modulator) for DVB T/H (DMB 2018)
DMB-2018 DVB-T Exciter supports all the DVB-T & DVB-H mode, supports hierarchical and non hierarchical modes. The Exciter has digital linear and non-linear pre-correction functionalities. Which can directly excite the DTV transmitter. The RF output is from 173MHz to 858MHz with a step of 1Hz. The Exciter has 1pps and 10MHz inputs, supports MIP remote parameter configuration. Furthermore, it can adjust inner delay according to MIP TPS to synchronize with other exciters in the same SFN. DMB-2018 DVB-T Exciter is the best choice for the Digital Terrestrial operators.
