The 7751TG2-HD Test Signal Generator modules provide a cost-effective method of generating 1.5 Gb/s HDTV 4:2:2 and 4:4:4 test signals. The 7751TG2-HD is ideal for checking signal path integrity, or to determine system performance over varying cable lengths. The 7751TG2-HD generates test signals in a wide variety of HDTV video formats. In single link mode, the 7751TG2-HD outputs a SMPTE 292M 4:2:2 test signal on two outputs and a selected SMPTE 292M 4:2:2 black signal on the remaining two outputs. In dual link mode, the 7751TG2-HD outputs a SMPTE 372M 4:4:4 test signal on two dual-link outputs.
