Product Description
1, Outline
DVB - S2 modulator is according to European satellite Communications systems digital video broadcast second Generation DVB - S2 (standard EN302 307) and develop High-performance modulator. The modulator standard USES More advanced channel coding technology and high order Modulation than DVB-s combined, in the same transmission Conditions increased transmission capacity, and able to be in the Same spectral efficiency provided under stronger receiving Ability.
This equipment in RF output, can be directly l-band satellite Communication system with digital TV transmitter facilities, and Decentralization DVB-s (EN300421) various work mode, to Support local and remote configuration modulation parameters
