DVB-S/S2 Dual Monitoring Blade


Product Summary

The VB272 input card offers monitoring and analysis of QPSK/8/16/32APSK signals found in DVB-S/S2 satellite transponders. A chassis can be equipped with a VB120 or VB220 PROBE controller and up to two VB272 input cards under its control.

A complete configuration with a fully licensed VB120 and two VB272 interface cards provides real-time monitoring and alarming for up to four DVB-S/S2 RF inputs, 10 IP MPTS/SPTS multicasts (upgradable to 50 streams) and one ASI TS input and output. Full ETSI TR 101 290 analysis is performed on all DVB-S/S2 inputs, the ASI input and the IP input in parallel. If the VB220 PROBE is used as a master card the IP monitoring capacity is increased to impressive 260 MPTS/SPTS multicasts. The VB272 DVB-S/S2 card is delivered with one input and the second input can be enabled by a simple license upgrade.

Together with the VB120 or VB220 controller, the operation of the VB272 is via an intuitive web interface, a GUI providing a graphical overview of scanning status and ETR290 TS data as well as a full constellation diagram of the transponder together with all relevant RF levels.
