8PSK/DVB-S2 Modulator (950-2150MHz)
Product Overview
The DVB-S2 modulator adopts advanced frame structure, channel coding and modulation technologies.
Under the same transmission conditions, it provides 50% higher transmission capacity than DVB-S,
with superior receiving performance at the same spectral efficiency.
This modulator complies with DVB-S2 (EN302 307), the second-generation standard for digital video broadcasting over satellite communications in Europe.
It supports 2×ASI or 1×IP input and outputs signals via 8PSK/DVB-S2 modulation,
making it one of the core devices for terrestrial wireless and satellite modulation applications.
