The TM7920-LB is the next generation L-BAND High-Tech Broadcast DVB-H / DVB-T modulator, performing Superior outstanding MER QUALITY and World-Modes SFN-MFN modulations, bands & frequencies. The modulator comes standard with two broadcast-grade simultaneous IF/RF signal outputs with harmonics and spurious better than <65dB, one IF 70 Mhz suitable to drive any existing DVB-H broadcast transmitter from the IF input, and one fully agile @ 1Hz steps ranging from 1400 Mhz to 1700 Mhz ( other custom ranges available upon request ) with adjustable level from -20 dBm to -8 dBm and suitable to drive directly any existing L-BAND DVB-H RF broadcast amplifier ( transmitter ), . The TM7920-LB has built-in Linear and non-linear precision precorrector controlled from both the rack-frame display and the remote sites via WEB so no special software is needed on the remote PC but a standard web browser. The modulator has 2 Hierarchical ASI inputs ( high / low ) , 1 ASI Fail-over backup input, 1 ASI loop output, SFN in both standard and hierarchical modes, Full MIP support, MFN, 10Mhz and 1PPS inputs for SFN operations, 5/6/7/8 Mhz Bandwidth, DVB-T / DVB-H selectable with 2/4/8K, all modulation modes to deliver up to 31.5 megabit/s ASI data input, RS232 + WEB + SNMP control, built-in activable RF test patterns and PBRS for R&D and systems stress-tests, auto-rate adaptation on all ASI inputs, fully software-upgradable through simple internet firmware download, selectable control language as English, Spanish, French, Chinese, and other ( ask for availability ) The TM7920-LB is fully compliant with all-modes DVB-T and DVB-H standards and is already operational at hundreds sites of important telecom, broadcast, mobile companies with hundreds of channels on-air, as well it is used at many R&D and Testing depts. of important world-wide DVB-T / DVB-H receivers and chips manufacturers companies as reference generator |
