DVB QPSK Modulator

Outline: 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.Feature : Complying DVB-SETS300-421 QPSK modulating standard . If output frequency range 950MHz 2150MHz (it can be set as users' needs) Build-in frequency synthesizer, support uplink frequency conversion in U .band .450 950MHZor L band 950 2150MHz Ports complying ASI, SPI standard.
