Leader LT4600A Multi-format Video Generator

The LT4600A is a compact multi-format video sync and signal generator in a 1U half-rack chassis. It supports triple-rate SDI, generating 3G-SDI (Level A and Level B), HD-SDI including dual link, and SD-SDI from two outputs whose pattern and timing can be set independently. That makes it a flexible reference and pattern source for a studio, OB truck, or QC bench.

A genlock input locks the generator to an external reference, either NTSC/PAL black burst or HD tri-level sync, and three pairs of independent black burst outputs feed a facility's sync distribution. It embeds up to 32 channels of audio on 3G-B (16 on 3G-A, HD, and SD), provides two AES/EBU outputs and a word clock at 48 kHz, and overlays ID characters, a QVGA logo, and safety area markers. It runs from a universal AC supply.
