| TLQPM-3 Trans Modulator |
|
TLQPM-3 QPSK to QAM modulator is a high performance equipment combining QPSK decoding with QAM modulation . It receives DVB transport stream from satellite receiver, encode, multiplexer, DVB gateway, scrambler, video server etc and provide IF or RF output after RS encoding, convolution interweaving process and QAM modulation. This transformer is mainly used in digital cable TV head end system to transfersatellite signal into cable TV network, which further saving the amount of satellite decoder, digital multiplexer and providing an economical solution. It can also be used an a pure QAM modulator when receiving the DVB-ASI input stream

| TLQP-3 QPSK Modulator |
QPSK digital TV modulator adopts advanced digital signal processing technology, of which receiving port can directly use digital satellite receiver for receiving, thus fully complying DVB-S standard. Not only can it gain relatively high frequency spectrum usage ratio, having very strong anti-interference and relatively high price performance ratio, but also it can well comply analogue FM microwave equipment.
QPSK digital TV modulator adopts various processing method, such as random energy spread processing, RS coding, convolution interweave, contracting convolution coding, and pre-modulating baseband shaping processing, etc. all these contribute a high guarantee to the data transmitting performance.
