BM6500 & BE6500 Orion DVB-S/S2 Modulator

Orion is a state-of-the-art modulator designed for satellite operations in full compliance with the DVB-S, DVB-S2, and DVB-DSNG standards. It provides operators with best-in-class performance as measured by SNR value, excellent shoulder levels, and low phase noise, achieving full L-Band (950/2150 MH) or IF Band (50/180 MHz) coverage with a useful bit rate up to 160 Mbps. Input MPEG-TS streams can be received over either ASI or IP. Control is over IP via an embedded Web server or through standard SNMP monitoring and control systems. The Orion modulator is designed to deal with the physical layer scrambling requirements of ETSI EN 302 307. It can operate in CCM (Constant Coding Modulation), as well as VCM (Variable Coding Modulation) and ACM (Adaptive Coding Modulation) modes with appropriate system devices. Orion pairs exceptionally flexible input bit rate adaption—with choices between PCR adaption, Padding insertion, Null Packet Deletion & Padding Insertion, and Dummy BB Frame insertion—with a high output baud rate (up to 68 MBaud), fully feeding a 72 MHz transponder to increase the OPEX of the satellite link. An internal PRBS generator can be used to generate a RF spectrum without any valid signal input.
