VB256 ISDB-T Terrestrial RF Input Module

The VB256 ISDB-T input module expands Bridge Technologies’ digital terrestrial monitoring capabilities to encompass the Latin American and Japanese Terrestrial markets. Supporting both ISDB-T/SBTVD-T standards it will enable customers operating in these regions to fully monitor their ISDB-T transmissions.



Two modules may be housed in a 1RU chassis together with a controlling VB120 or VB220 probe, providing high monitoring capacity occupying a minimum of rack space. The VB256 will enable the monitoring of multiple RF parameters, supporting 6, 7 & 8 Mhz channels.

The demodulated Transport Stream is then presented to the card’s ETR 290 engine for full priority 1, 2 and 3 analysis. Each VB256 card has two independent inputs allowing two channels to be monitored continuously. Multiple channels may also be assigned to a VB256 input allowing the tuner to cycle round up to 50 channels providing a dense yet compact monitoring solution.
