VB272-SMA

The VB272-SMA



Pictured is a typical setup with a VB120 controller containing SFP based Optical GigE or Electrical 10/100/1000T Ethernet interfaces, separate 10/100/1000T management interface, USB-RS232 for initial  setup and status LEDs with 2 * VB272 DVB-S/S2 units in a 1"RU EC Redundant AC powered chassis. This configuration only use 25W of power giving additional OPEX savings.

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 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 constelation diagram of the transponder together with all relevant RF levels.

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 DVB-S/S2 multiplexes, making it possible to monitor a complete transponder using a single VB272 interface card.

The VB272 also comes equipped with full power/tone control of RF input switches and can also use the DISEqC 1.2 protocol for additional switch control. With support for modern modulation types as 16 or 32 APSK, the VB272 is future proof.

The VB272 is delivered with standard 75 Ohm F-Connectors or as an optional factory ordered VB272-SMA with 50 Ohm SMA Connectors.
