Overview
NDS2403G ATSC-T modulator is DEXIN’s newly designed product supporting DVB-ASI and SMPTE-310 input. After modulating the inputting signals through ATSC 8-VSB, it can output RF signals with the range between 50~860MHz. In other words, NDS2403G ATSC-T modulator supports the coding and modulating mode under ATSC-T A/53 standard. It also supports adaptive non-linear and linear digital pre-distortion (DPD). Additionally, the system of this device can be on line controlled and upgraded through network, which can be widely used in ATSC-T digital broadcasting network setup and the testing for ATSC-T set Key Features: Full complying with ATSC A/53 standard; Dual channel DVB-ASI/SMPTE-310M input, automatic switch-over and hot backup; Dual IP input ports, GE ports, over UDP/RTP; RF range: 50MHz~860MHz,1Hz stepping; Front panel and IP remote control; RS coding, data interleaving, Trellis coding; Supports adaptive linear or non-linear digital pre-distortion (DPD); Adopts constant-temperature crystal oscillator, the frequency stability can be up to 0.1 PPM; Excellent RF output performance: EVM, MER, SNR, shoulder level and etc.
