VB12-RF PORTABLE BROADCAST PROBE

The VB12-RF covers all the monitoring needs encountered in hybrid IP multicast, OTT and RF networks. The unit is particularly suited for use in FTTH IP multicast scenarios or at regional points of presence in cable architectures where IP and QAM is encountered. The VB12-RF has further use in ATSC terrestrial networks where 8VSB is used as modulation method.

Further to this the VB12-RF comes with powerful functionality for monitoring OTT streaming formats such as Microsoft Smoothstream, Apple HLS, Adobe HDS and MPEG-DASH making it ideally suited for also inspecting these new modern formats of ever increasing relevance to anybody involved in television distribution.


Figure - The VB12-RF is portable and ideally suited for fault finding video issues in IP multicast, OTT and QAM networks

The VB12-RF understands SCTE-35 digital queue tones as used in local program insertion architectures and will log and analyse signals carrying this type of signalling.

The included T2MI functionality offers T2MI protocol monitoring and analysis and is of use in DVB-T2 scenarios.

The protocol analysis is available on the IP and the ASI input interfaces.

The VB12-RF interfaces are Gigabit Ethernet, ASI and QAM/VSB RF inputs as well as a separate Gigabit Ethernet management interface for easy connection to either a laptop or the management network.

There is also an SMA input for 1PPS timing reception as used in DVB-T2/T2MI scenarios.

Common for all input formats is the ETSI TR 101 290 analysis. Priority 1, 2 and 3 analysis is performed, with the addition of a number of useful checks defined by Bridgetech. PSI/SI or PSIP is parsed and the result displayed as a high level information tree, with the possibility of detailed examination (hex dump).

The VB12-RF is also capable of extracting thumbnails from any of the input streams. It is possible to make a recording of a service, or it can be forwarded to a remote destination via the Ethernet data or management port for further content analysis. Innovative functionality makes it possible to directly compare signals across different probe interfaces.

RF specific parameters are measured and analysed, and alarms are raised if measurements are not within user-specified limits. Measurements include MER, SNR, BER and signal level. A QAM/VSB constellation diagram is displayed to visualise symbol integrity.

News DEFAULT FEATURES
The VB12-RF comes pre-configured from the factory with the following options already included:
  - IP-OPT for multicast monitoring of up to 10 IP multicasts
  - ETR290-OPT for TR 101 290 analysis on IP (one engine), ASI and QAM input
