DVB-T DVB-H Terrestrial Modulator
        NN6-1161

NN6-1161 DVB-T DVB-H Terrestrial modulator performs broadcast quality COFDM modulation according to DVB-T standard. With its DVB-H option and an integrated RF Up Converter (in both VHF and UHF bands) options, ENENSYS DVB-T / DVB-H Terrestrial Modulator is a powerful means to perform field test, mobile receiver application development and validation, smart demonstrations.

It is optionaly possible to have a USB2.0 input on rear panel of the device to directly play an MPEG-2 Transport Stream from a PC, without needing professional stream player.


Applications:
     - DVB-T or DVB-H Broadcast
     - R&D development of DVB-T or DVB-H equipment
     - Test & validation of fixed or mobile receivers
      - Easy demonstrations and roadshows around TV on mobile

  • DVB-T Terrestrial Modulator with integrated RF up-converter
    NN6-DVB-H option for DVB-H compliance to address mobile receivers
    Broadcast quality


  • USB2.0 input option
    embedded USB2.0 to DVB-ASI converter with stream player application (Windows XP, Windows 2000)


  • Applications: test and validation, development, broadcast
    Fields: tuner validation, Set top box testing, shows, R&D lab


  • Supports hierarchical input mode as recommended by DVB-H DVB-T
    High and Low priority MPEG-2 stream inputs
    Separated modulation schemes for each input


  • Support both Frequency Network modes:
    MFN     and SFN modes (DVB-T, DVB-H)
    Seamless switching (SFN mode)
    External synchronization (10MHz and 1pps GPS) for SFN


  • Supports 5, 6, 7 and 8MHz bandwidth
    dynamically switchable on the fly (no need for cold reset)


  • Enhanced ASI input stage - on each priority:
    Redundant ASI inputs ( 2x ASI inputs per priority, automatic switching)
    188/204 bytes per packet accepted (burst/continuous)
    FEC processing and error correction
    PCR restamping
    TS bit rate adaptation
    Very low switching/setup time to run test batches on receivers


  • High end processing of input MPEG TS before modulation:
    MIP processing (Megaframe Initialization Packet for DVB-T or DVB-H Single Frequency Networks) and external synchronization
    NIT automatic update
    TPS Signalling
    Static/dynamic delay insertion to adapt terrestrial networks


  • RF output model:
    1x main RF output (VHF+VHF)
    1x monitoring RF output (VHF+UHF)


  • IF output model:
    1x main IF output (between 30-40MHz)
    1x monitoring IF output


  • I & Q output model:
    1x I output
    1x Q output


  • Optional Linear and non-linear Digital Precorrection
    Optional SNMP alarm trap sending


  • Remote control
    10/100bT ethernet interface
    Embedded TCP/IP server
    Control & Command client software


  • Compact equipment
    Robust and Portable
    19'' 1RU rack mountable
    Alarm management
