CS***1 DVB-S2 Uplink Modulator
Outline
CS***1 DVB-S2 uplink Modulator is compatible with DVB-S2 (EN*****7)
standard, adopts advanced framing structure, channel coding and
modulation technology, increasing over *0% transmission ability
more than DVB-S modulator under the same transmission condition and
also providing a more powerful receiving ability in the same
spectral efficiency. Meantime it is backwards-compatible with DVB-S
(EN*****1) modulating standard and has RF *0MHz & *4V/2A DC
coupling out.
Features
1. Fully complying with DVB-S2(EN*****7) standard
