Product Description
QAM Modulator
Outline
In the broadcasting process of digital TV programs, QAM modulator mainly complete QAM modulate and up-frequency conversation process for TS stream, Apply to multi-level transmission, broadcasting of digital TV business.
QAM modulator mainly used in head end of digital TV broadcasting, it is composed by two modules QAM modulator and digital up-frequency conversation, modulate the input serial or parallel TS stream via the QAM modulator module, modulate to IF frequency, then pass the up-frequency conversation module to frequency transform, into standard channel or supplement channel which meet demand. Finally mixed enter into CATV network, and received by the terminal STB.
Features
* Support IYU-T. 83A
* Error correct encode completely meet DVB-C standard
* Be workable under QPSK, 16QAM, 32QAM, 64QAM, 128QAM, 256QAM mode
* Input interface: ASI and SPI (DS3/E3 optional)
* Input date bit rate range: 1.5~51.6Mbps
* Output data bit rate range: 2~56Mbps
* Output signal Bandwidth(BW) range: 1.15~8.05MHz(roll down coefficient is 0.15)
* Output data symbol rate range: 1~7Mbaud/s
* RF frequency range: 110~862MHz
* Output level range: 95dBuV~115dBuV (stepping -0.5dB/step adjustable )
* 188/204 packet length adaptable itself
* Adopt big enough cache design, ASI interface support paroxysmal and symmetrical input TS stream, and can equilibrate and reforming the TS stream, enhance the efficiency of output TS stream.
* Input data empty packet filtering and output data fill in.
* PRC proofread function, can accurately correct several PCR of input data separately.
* Real time inspect and display for the efficient TS stream.
* Adaptable itself to filtering circuit design to ensure the excellent suppress capability out of band.
* -20dB RF test mouth to monitor IF output.
* Fault alarm display
* LCD screen display
* Network control interface, make centralize management, remote upgrade and maintenance (network management software only for option)
* Power-off memory
