LT4670 - 1U full-rack width synchronous SDI/IP reference and test signal generator


Category IP Broadcast Solutions - QC QA Monitoring

The Leader LT4670 is a newly designed 1U full-rack width synchronous SDI/IP reference and test signal generator, designed for use in film and television studios, mobile production vehicles and postproduction houses. Designed to ease customer’s migration from SDI to IP, a host of optional features offers customers the freedom to invest in advanced tools as and when they need them. Connectivity capabilities provided as standard include six independent analog synchronous signal outputs, digital audio outputs, word-clock outputs and LTC in/out.

These can be supplemented by versatile of options such as GNSS synchronization, PTP synchronization, 4K quad-link, 12G-SDI, 3G-SDI, HD-SDI and SD-SDI outputs and 25G IP stream interface in any combination, allowing optimal management of synchronous systems.

The standard LT4670 toolset includes genlocked black burst signals and tri-level sync pulse generation; stay-in-sync function in the event of an error in the incoming genlock signal; low-lock stabilization when returning to genlock from stay-in-sync; 48 kHz word-clock signal output synchronized to incoming video, and synchronous control between devices (L-SYNC). Preset and memory functions are included. Power supply and fan units are hot-swappable to ensure workflow continuity. Optional features include GNSS synchronization, PTP synchronization as well as support up to four multi-rate SDI test signal outputs (up to 12G) plus two 10G/25G Ethernet ports for ST 2110 test signal streams with ST 2022-7 redundancy. Lip-sync pattern allows measurement of video and audio timing discrepancies on SDI signal transmission, and User pattern allows customer‐generated BMP and TIF images to be used as test patterns.

Superimposed embedded audio allows 16 channels of embedded audio (four groups of four) to be superimposed as well as Timecode pattern display can be superimposed at any position on the screen. A Freeze confirmation function allows scrolling patterns, moving boxes, scrolling ID character flashes or flashing circles to be superimposed on patterns.
