TV station monitoring of their own broadcast signals
Tracking RF quality to make decisions on transmitter alignment and maintenance
Validating ATSC 3.0 transitions from ATSC 1.0
The VB258 is a quad port RF blade with worldwide support for terrestrial and cable digital RF standards, and it is an integral part of the Sencore VideoBRIDGE monitoring system. Each blade has four separate RF inputs that enable monitoring of digital terrestrial and cable RF transmissions, including support for ATSC 3.0. Two VB258 blades can be installed in a single 1RU chassis together with a controlling VB120 or VB220 probe, providing eight RF inputs and a high monitoring capacity occupying a minimum of rack space.
Full RF parameter monitoring is included for each RF input and tuning for each input can be fixed on a single channel or round-robin amongst multiple channels. The Advanced RF Option adds impulse response graphing and analysis to the VB258, making it possible to check signal reflection conditions at the probe location.
The full suite of digital terrestrial and cable RF standards supported include ATSC 1.0, ATSC 3.0, DVB-T, DVB-T2, ISDB-T(b), QAM-B, DVB-C, DVB-C2, and others. In addition, T2MI analysis is an option in the controller probe blade.
All this RF analysis functionality is complemented by the renowned VideoBRIDGE ETSI TR 101 290 monitoring engines, which provide priority 1/2/3 measurements of the streams carried in the RF to ensure standards conformance at all levels of the signal.
