QPSK Modulator

QPSK6300 is a high prefessional quality and high stability digital headend transcoder that accepts transport stream according with DVB-S does processing such as RS encoding, scrambler, interleaver, I/Q modulator, wave filter,finally upconvert intermediate frequency signal into RF signal,and transmit the signal onto any desired CATV or off-air output channel between 450-950MHz and 950-2150MHz.

Key Features: According for DVB-S ETS 300-421 QPSK modulator standards,performance on the FPGA.

Variable Symbol Rate from 0.1 to 45 Mbaud High MER Output Signal Quality and Phase Noise of Best Performance Support edition and generation of all PSI/SI tables Support PID filtering,modifying and remapping Chinese/english LCD display,flexible in operation SNMP management,RealTime Remote control and diagnostics L frequency agile 450-950MHz and 950-2150MHz High reliability design,stable in running Applications: DVB-S MMDS/MUDS Remote education and /Bussiness TV Image monitor/NVOD/VOD Technical Specifications DATA INTERFACES 2 ASI Input Accordance to EN50083-9 Connector: BNC,75ohm Bit Rate: ≤108 Mbps Packet Format: 188,204 bytes RF INTERFACE RF OUTPUT 1x RF output Connecter: F-type(or BNC-type),75ohm Output Frequency Range: 450-950MHz and 950-2150MHz Phase Noise: ≤ RF Level: 110—120 dBuV, Step 0.5dB Symbol Rate:0.1-45 Mbaud RF TEST-POINT Connecter: F-type(or BNC-type),75ohm RF Level: 90—100 dBuV, Step 0.5dB CHANNEL ENCODING Contellations: QPSK MER: ≥ 14dB BER: ≤ 0.5 x 10 -9 SNR: ≥ 48dB Randomisation encoding: RS Trellis and Interleaving according to ITU-T Annex A,B,C FEC Encoding:1/2,2/3,3/4,5/6,7/8 PROCESSING PID filtering and modify PCR de-jittering and re-correcting PSI/SI modify and generation Adjustable bitrate accordance to configuation reference CONTROL INTERFACE Front Panel control for local operation.
