2Overview
2.1Function and Application
DVB-S2 modulator supports 2×ASI input and outputs DVB-S2 RF signal by QPSK/8PSK
modulation. It uses advanced frame structure, channel coding modulation technology. Compared
with DVB-S modulator, it increase 50% of the transmission capacity under same condition and it
has stronger reception capacity under same spectral efficiency. This modulator complies with
DVB-S2 EN302 307 and DVB-S (EN300 421) standard. It suits 1U rack and can be configured
by front panel LCD and NMS (network management software). Its high-integrated and
cost-effective design makes it widely used in varieties of digital wireless and satellite
broadcasting distribution systems.
