ZBL9020A QAM Modulator (ZBL9020A-JF/JH/JL )
ZBL9020A-JF:
1 Large-scale data transmission speed with the range of input code stream: 1Mb/s~216Mb/s
2 Supports Physical broadband: 1.3~8MHz
3 Constellation: QPSK/16/32/64/128/256QAM
4 Totally comply with ITU-T J.83
5 Coding rate modulation: supports the adding & deleting of empty packages.
6 Agility or fixed frequency of output RF: 47~862MHz
7 Output level: >115dBÃ×V(RMS)
8 Excellent Phase-noise index
9 Front control panel with control buttons and LCD display screen
10 Network management interface: users can actualize a series of network functions such as centralized network management, remote upgrade and main-tenance; the interface supports the control of QAM constellation, modulation symbol rate, frequency of output RF and output spectrum£ªs polarity; through the interface, user can also monitor the total code rate, net code rate & package length of input transmission stream, properties of input interface and net code rate of modulation output.

ZBL9020 Series QAM Modulator is the absolutely necessary transmission equipment for DTV network. TS data comes from SDH trunk network or from local equip-ment such as MPEG2 video server and multiplexer, is transmitted into QAM Modulator for error correct coding and QAM modulating, and then QAM Modulator outputs RF signals and transmits them to the CATV network (47MHz~862MHz). It provides ASI & SPI interface that compatible with DVB-C standard, and/or provides DS3 interface which is compatible with many foreign manufacturers. In addition, it has a data-communication interface for both the local and remote network management.
