Product Name: Digital Head-End 4 in 1 Qam Modulator CATV Wdq-3244 Model NO.: WDQ-3244 Condition: New Certification: CE Type: TV Front-end Equipment Ts Packet Format: 188 or 204 Modulation Scheme: Qpsk,16~256qam Trademark: Prevail/Fobetmoc Transport Package: Pearl Wool Specification: 1RU Origin: China HS Code: 85437092 Product Description DescriptionWDQ-3244 4 in 1 QAMis a new compact (1RU only) chassis and cost-effective QAM modulator, which isdesignedby Hangzhou Prevail according to the DVB related standards. This device is integrated up to 4 channel QAM modulating carrier outputs, in which each carrier has independent signal channel encoding and direct RF output. Hence, one PCS 4 in 1 QAM modulator can work as 4 standalone QAM modulators, significantly reducing the network operators' head-end cost.WDQ-3244has 4 ASI input, RF output and RF testing output. The WDQ-3244has very convenient and friendly managementinterface, the user can complete all operation via local keyboard and LCDdisplayon device, or accessthrough the Ethernet port on device.Features4 adjacent channel QAM carrier4 ASI inputs,TS packet format input automatic detection (188 or 204 bytes)RF output power 90~100dBuV ( with 0~10dB adjustable attenuation range) and 48~863MHz frequency range16~256QAM modulation modesProvide RF output monitoring port (-20dB)Adjustable Symbol Rate: 5 to 7MbaudPSI/SI tables synchronization updateExcellent RF output performance, MER≥40dBMemory protection for power-failLocal keyboard control and LCD display, or access via Ethernet linkApplicationDVB-C QAM modulationCompatibleEN 50083-9ETSI TR 101 154ETSI TR 101 891EN 300 429(DVB-C)ITU-T J.83ARecommended Operating ConditionsStress in excess of the maximum absolute ratings can cause permanent damage to the device (See Table 1)Table 1 - Recommended Operating Conditions ParameterSymbolMin.Max.UnitSupply VoltageNoteV90250VSupply FrequencyF4951Hzpower consumptionC40WAmbient Operating TemperatureTw0+50°CStorage TemperatureTs-25+55°COperating HumidityH1075%Note: Support both 110V and 220V supply voltage standards, but please let us know which one do you need when you release order.SpecificationsTable 2 - Technical SpecificationsParameterSymbolDescriptionUnitRemarkMechanical dimensionHeightH42mmabout 1UWidthW434mmabout 17"DepthD340mmASI InputNumber of ASI input-4Impedance-75WConnector-BNCNATS packet format-188 or 204ByteAutomatic detectionTransmission format -Data packetNARF OutputImpedance-75WConnector-BNCNAFrequency-48~863MHzOutput level-90~100dBuVAdjustable attenuation of 0~10dBModulation SpecificationModulation scheme-16/32/64/128/256QAMNASymbol RateSR5≤SR≤7MbaudBandwidthBW≤8MHzModulation Error RateMER≥40dBAfter equalizer, 64QAMBit Error RateBER≤1x10E-8After FEC, 64QAMCarrier to NoiseC/N≥45dBCarrier suppression-≥58dBPhase noise-@10KHz≤-80dBc/Hz,@100KHz≤-100dBc/HzProcessCompany Profilecontact us
