input option offers monitoring and analysis of QPSK/8PSK signals found in DVB-S and DVB-S2 satellite transponders. The chassis can be equipped with a single VB120 or VB220 IP-PROBE controller card and up to two VB270 QPSK input cards under its control. The complete configuration with the fully licensed VB120 provides real-time monitoring and alarming for two QPSK/8PSK RF inputs, 10 IP MPTS/SPTS multicasts (upgradeable to 50) and one ASI TS input. ETSI TR 101 290 analysis is performed in parallel for QPSK/8PSK inputs, the ASI input and the IP input. If the VB220 is used as master card the IP monitoring capacity is increased to impressive 260 MPTS/SPTS multicasts. The combined unit is ideal for hybrid networks where IP is used as a carrier from head-end to the satellite uplink station.The built-in round-robin functionality allows sequential analysis of multiple QPSK/8PSK multiplexes, making it possible to monitor a complete transponder using a single VB270.
