SCPC Wideband DVB-S2X SDR Platform

SatixFy SCPC Modem (Single Channel Per Carrier) provides high-end capabilities in a compact design. It supports a single carrier of 125 MHz both in the forward and return links (Point to Point). The SatixFy SCPC Modem can operate in trunking mode (L2 Bridge) as well as a Layer 3 router and has GSE, MPE and Baseband Frame encapsulation options. Extended dynamic range of 30 dB SNR supports various modulations from VLSNR (-10 dB) up to 256 APSK (+20 dB). The SCPC Modem is based on the SX-3000 Software Defined Radio (SDR) ASIC, enabling wide verity of applications. The modem is also available in 1U rack mount enclosure.
