Qpsk Digital Tv Modulator

Our offered superior quality JXDH-6502 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.

JXDH-6502 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.
