NAB Show 2024: Leader Instruments presented new SDI/IP test signal generator LT4670. Housed in 1U full-rack case LT4670 it designed for use in traditional SDI broadcast facilities as well as the next generation of hybrid SDI/IP facilities.
   

Leader LT4670 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 options such as GNSS synchronization, PTP synchronization, 25G IP, 12G-SDI, 4K quad-link, 3G-SDI, HD-SDI and SD-SDI outputs in any combination, allowing optimal management of synchronous systems.

The standard LT4670 toolset includes genlocked black burst signals and tri-level sync pulse generation; a ‘stay-in-sync’ function in the event of an error in the incoming genlock signal; slow-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 also included. Auxiliary power supplies and fans can be hot-swapped into the unit to ensure workflow continuity.

The LT4670 offers customers the freedom to invest in advanced tools when needed. Optional features include GNSS synchronization, PTP synchronization, support for 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. The Lip-Sync Pattern option allows measurement of video and audio timing discrepancies on SDI signal transmission. The User Pattern option allows customer‐generated BMP and TIF images to be deployed as test patterns. Superimposed Embedded Audio allows 16 channels of embedded audio (four groups of four) to be superimposed. 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.
