Description

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
