JXDH-6513 DVB-S2 modulator which is a high performance modulator is developed according to the Europe satellite communications system digital video broadcasting second-generation standard DVB-S2, the modulator standard adopts more advanced channel coding techniques and higher order modulation combination, in the same conditions it increases more 50% transmission capacity than DVB-S, and can provide a more robust receive ability under the same spectrum efficiency. The device's RF output is in the L-band, can directly form a complete set with satellite communication system's digital TV transmitter. And downward compatible DVB-S's all kinds working modes support local and remote configuration modulation parameters.

      Fully compliant to DVB-S2 Broadcast mode and DVB-S

     Supports symbol rate of 1~30Msps(DVB-S2), 1~45Msps(DVB-S)

     Supports FEC rate of 1/2,3/5,2/3,3/4,4/5,5/6,8/9,9/10(DVB-S2), 1/2,2/3,3/4,5/6,7/8(DVB-S)
