DMB-2118 is an excellent high-end DAB/T-DMB modulator fully supports DAB and T-DMB standards and can be used to build various kind of DAB network, T-DMB network and Mobile TV network. DMB-2118 supports MFN and SFN operation modes, and has digital linear and non-linear functionalities. It also integrates an high performance up converter which has agile Band III VHF output and optional has L-Band output. The modulator is the best choice of digital audio and mobile TV operators. Compliant with ETS300401,300799 and Eureka-147 DAB Modes I,II,III and IV modes supported Powerful ETI inputs management SFN and MFN operations support Linear and non-linear pre-corrector supported Dynamic reconfiguration supported Web browser remote control, SNMP is optional SPECIFICATION Inputs ETI inputs  Compliant with ETS 300799 standard 2x ETI redundant inputs, Connector: 75ohmBNC NI(G703) or NA (G704) network framing supported (auto detection) Bitrate:2048kbits/s?¨¤50pp RS error correction (NA only) Max delay for static delay:1s(MFN only) Max delay for off set delay:1s(SFN only) ETI input management Redundant inputs with automatic switching Signal Processing DAB Transmission modes I, II,III,IV (accordingtoETS300401 standard) Dynamic reconfiguration Yes MNSC control Transmitter Offset Delay and TII Network mode SFN & MFN Clock & Synchronization Internal 10 MHz clock High quality internal clock (TCXO) External 10 MHz reference Connector: BNC Level:-5to+10dBm Impedance:50ohm External 1PPS Reference Connector: BNC Level: TTL level-5 Kohms Min Pulse width: 1s SFN synchronization accuracy 200ns Outputs Connector Two Connector, 50ohm N-type Frequency Adjustment range 174 MHz to 240 MHz, in1Hzstep Main Output Level Signal: 0dBm Attenuation: 0 to10 dB in 0.1 dB step Level Stability: 0.1dB/10 15dB Monitoring Output Level Signal:-20 dB Attenuation: 0 to10 dB in 0.1dB step I/Q amplitude unbalanced I/Q quadrature error 40dB 50dB 50dB Test Modes ETI test stream Internal generation of ETI Loaded test stream Synchronization test mode Locate the ETI0 frame Central carriers cancelled 19 carriers located in the middle of the spectrum are cancelled.
