Leader Electronics, a test and measurement instruments provider, has announced major additions to the feature set of its LVB440 IP Analyser.
The LVB440’s IP traffic and signal monitoring resources are now supplemented by signal generation tools, plus the ability to monitor and analyse “SR Live Metadata”. These follow on from the expansion announced in Q4 2021, which added support for JPEG XS ST 2110-22 compression analysis, closed captioning measurement, 7.1 and 5.1 surround sound, and loop-mode continuous capture of data packets.
With its new signal generation facilities and “SR Live Metadata” toolset, the LVB440 offers increased efficiency in evaluating network performance. Operators can create placeholder reference signals locally using the integral graphical user interface (GUI) or remotely via the Networked Media Open Specifications (NMOS).Standard dynamic range (SDR) and high dynamic range (HDR) signals such as chroma bars can be configured for specific video resolutions or refresh rates, including a user-definable video or audio indent, saving time during system setup or alteration.
The LVB440 is controlled via an HTML-5 browser and provides full support for up to eight local or remote users. It gives production teams the ability to perform real-time checks on large numbers of streams and multiple resolutions in parallel at multiple locations. Operators can survey every media transport layer of an IP network simultaneously, allowing issues to be rectified before they impact the quality of service experienced by programme viewers.
When connected to primary and secondary networks, the LVB440 can monitor and analyse redundancy within the SMTPE ST 2022-7 standard, which is used to ensure protection switching. Tools are also provided for PTP clock analysis, including clock source detection, timing accuracy and individual flow path-latency. SMPTE ST 2110, ST 2022-6, ST 2059-2 PTP standards, and NMOS are also supported.
