Bascom Hunter’s DVB-S2X Modem VPX Card is a SOSA-aligned 3U VPX card that implements a modem for DVB-S2X. Digital data in both directions use the Digital Intermediate Frequency Interoperability (DIFI) v1.2 packet standard over a 40G Ethernet interface. Analog data is tunable over the L-Band frequency range. This high-performance card supports up to 125MSymbols/sec of data traffic and is easily configured using a network-accessed GUI or SCPI commands. The modem design uses a Xilinx/AMD RFSOC based on the Abaco VP431 VPX card.
