It’s a newest generation of professionals with a QAM modulator. Which is used for multiplexing the 8 channels input TS stream, scrambling the 4 channels, the output 4 interval 6MHz or 8MHz neighbor frequency RF(30MHz-900MHz) signal. So it’s a reliable front-end equipment for broadcasting operators and system integrators. Key Features  Constellation: QPSK,16, 32, 64, 128, 256QAM  (4 adjacent channel QAM carrier) Supports to input the 4 channels TS and multiplex to any channel among the 4 neighbor frequency channels, and support to scrambling the 4 channels.  Input data bit rate range: 1 ~ 216Mbps, the output data symbol rate range: 1 ~ 7Mbaud / s  High quality of MER and phase noise, pcr jitter of less than 50ns  PID filtering, modifying, remapping，NIT table generation, supports 45 frequencies NIT table reflection Max  Alternate and insert the SI table data, input the data empty packet filtering and output the data refilling  Adopt huge buffer memory design, supports ASI burst and consecutive input mode, realize to revise the output rate average  RF frequency range: 30 ~ 900MHz, step: 10KHz,output level: -20dBm~0dBm  High reliability design, stable in running, supports self-adaptation filter design, to keep advantage of out of band rejection.  With Ethernet interface, can control the QAM modulator remote parameter configuration, real-time monitoring of running status Applications  DVB-C broadcast headend network  Distance education and video conferencing  Video surveillance and video on demand Technical Specifications Data Interfaces ASI  8xASI Input, accordance to EN50083-9,,connector: BNC,75ohm  Payload Bit Rate: ≤51.6 Mbps  Packet Format: 188, 204 bytes RF Interface RF Output  1x RF output, connecter: F-type 75ohm  integrated up to 4 channel QAM modulating carrier outputs  Output Frequency Range: 30-900MHz  Return Loss: ≥15dB  Phase Noise: ≤ -95dBc/Hz@10KHz  RF Level: -20dBm-0dBm  Symbol Rate:1-7 Mbaud  Carrier suppression: ≥ 55dB  MER: ≥42dB RF Test-point  Connecter: F-type, 75ohm  RF Level: -20dB Channel Encoding  QAM Constellations: All constellations up to 256 QAM  IF MER: ≥44dB  SNR: ≥52dB  Error correction coding; (204,188) RS code  Randomisation encoding: RS Trellis and Interleaving according to ITU-T Annex A,B,C Processing  PID generate and modify, insert  PCR de-jittering and re-correcting  PSI/SI modify and generation  Input stream adaptive selection, the output stream configuration accordance with adaptive parameters Control Interface  Ethernet Interface: IEEE802.3 Ethernet, RJ45 interface, with SNMP network management protocol, or WEB  Front panel buttons to operate the LCD display in English, indicators lights showing Environment  Power Supply: AC 90-250V 50/60Hz  Power consumption: 50 W  Operating temperature: -10～50°C  Storage temperature: -10～75°C  Dimensions: 400mm (L) X483mm(W)X44mm(H)  Weight: 7kg Order Information QAM6248 8Mux 4 Adjacent QAM Modulator QAM6244 4Mux 4 Adjacent QAM Modulator Note: PCS 4 QAM modulator can work as 4 standalone QAM modulators reducing the network operators’ head-end cost.
