QAM modulator mainly used in head end of digital TV broadcasting, it is composed by two modules QAM modulator and digital up-frequency conversation, modulate the input serial or parallel TS stream via the QAM modulator module, modulate to IF frequency, then pass the up-frequency conversation module to frequency transform, into standard channel or supplement channel which meet demand. Finally mixed enter into CATV network, and received by the terminal STB. Features * Support IYU-T.83A * Error correct encode completely meet DVB-C standard * Be workable under QPSK, 16QAM, 32QAM, 64QAM, 128QAM, 256QAM mode * Input interface: ASI and SPI (DS3/E3 optional) * Input date bit rate range: 1.5～51.6Mbps * Output data bit rate range: 2～56Mbps * Output signal Bandwidth(BW) range: 1.15～8.05MHz(roll down coefficient is 0.15) * Output data symbol rate range: 1～7Mbaud/s * RF frequency range: 110～862MHz * Output level range: 95dBuV～115dBuV (stepping -0.5dB/step adjustable ) * 188/204 packet length adaptable itself * Adopt big enough cache design, ASI interface support paroxysmal and symmetrical input TS stream, and can equilibrate and reforming the TS stream, enhance the efficiency of output TS stream. * Input data empty packet filtering and output data fill in. * PRC proofread function, can accurately correct several PCR of input data separately. * Real time inspect and display for the efficient TS stream. * Adaptable itself to filtering circuit design to ensure the excellent suppress capability out of band. * -20dB RF test mouth to monitor IF output. * Fault alarm display * LCD screen display * Network control interface, make centralize management, remote upgrade and maintenance (network management software only for option) * Power-off memory
