QAM Modulator

Application The V-SHINE®NVQM4 4-channel QAM Modulator is a key component for the cost-effective deployment and running of brodcast service over cable networks.The NVQM4 can achieve four-way independent input TS streams and modulation,also provides static PSI/SI parsing and modification,PID filtering and remapping. It can be widely used in HFC,MMDS and the oher DTV networks.Business benefits Powerful processing core for multiplexing and modulationSupport PSI/SI Extraction, Generation and InsertionKey features Supports all major cable and telecom industry standard interfaces4 x TS Inputs, 1 or 2 RF OutputsSupports 4 / 16 / 32 / 64 / 128 / 256 QAMSymbol Rate 1-7MS/sQAM modulation to ITU-T J.83 Annex A and C with integrated upconversionFrequency range 50-860MHzRF output range 110-118dBuvSupport ASI, DS3 inputSupport PSI/SI parsing and editingSupport PID remapping and filteringFront panel control and displayUser friendly configuration via V- SHINE®NMDVS management systemSNMP support Interface Specifications ASI Input 4×ASI inputs Connector BNC, 75 Ω Option Input 4×DS3 inputs Connector BNC, 75 Ω RF Output RF×2(include RF test ourput interface) (all of the 4 inputs out of the main RF output) Frequency 50 to 860MHz Level 110 to 118dBuV Signal Specifications QAM constellations 16, 32, 64, 128, 256 QAM Symbol rate 1 to 7 MS/s Control Front panel and keypad: System settings and Alarm info.
