Leader Instruments Ships LV 7770 Rasterising Multi-SDI Monitor
Leader Instruments has announced the availability of its new LV 7770 rasterising multi-SDI monitor. First demonstrated at NAB 2012 and now deliverable, the LV 7770 incorporates all the test and measurement features of Leader’s award-winning LV 5770 multi-SDI field monitor in a compact unit which can be used free-standing or integrated into a studio desk. Leader’s LV 7770 enables programme production and postproduction staff, as well engineering supervisors in television and facilities, to check the quality of their video and audio content on a much larger screen than can be accommodated in a portable instrument. It has two auto-sensing 3G-SDI/HD-SDI/SDSDI inputs and can perform tests on a total of 17 video signal formats ranging from standard-deﬁnition up to 720p, 1080i and 1080p highdeﬁnition. Tri-level sync or NTSC or PAL blackburst are accepted for external reference. The selected input is reclocked and can be fed downstream. Fully controllable from its front panel, via Ethernet or from the optional LV 7770-01 dedicated remote control panel, the instrument employs a user interface essentially identical to the existing LV 5770, LV 5800 and LV 5700A. This ergonomic similarity allows operators to move easily between devices. The LV 7770 feature set encompasses waveform, vectorscope, peak video level display, SDI/external-sync phase difference, audio, picture and data monitoring functions. Displays can be viewed at full screen size or in assignable combinations. Extensive error detection and error logging facilities are incorporated, including gamut detection and a d j u s t a b l e e r ro r thresholds. Digital analysis screens Include data dump as well as equivalent cable length readings. Also available within the LV 7770 are Leader’s unique Cinelite II relative brightness analyser, 3D Assist stereoscopic signal evaluator, EIA-708/EIA-608 closed caption data display, active format description data display, optional physical layer testing and ancillary data display. A separate audio option card supports integral audio tools including Dolby metadata analysis and simultaneous display of 16 channels of SDI-embedded audio, audio loudness display and measurement of lip-sync timing. Composite signal monitoring, audio monitoring and eye pattern monitoring are available as optional extras. The rasteriser outputs test results and images through a DVI-I feed at XGA resolution, delivering high display quality. An HDMI output is also available and outputs picture plus audio to an external monitor for easy observation of source material. The Leader LV 7770 is DC powered to allow easy use on location and comes complete with an AC adapter. With the LV 7770 rasteriser, LV 5770 field instrument and the expandable modular LV 5800, Leader is now able to offer one test solution in three convenient configurations. ■
