7751TG2-HD
Dual HD-SDI Test Signal Generator with Embedded Audio
The 7751TG2-HD Test Signal Generator provides a cost-effective method of generating 1.5Gb/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 SMPTE 292M video formats. In single link mode, the 7751TG2-HD outputs a 4:2:2 black signal on two outputs and the selected 4:2:2 test signal on the remaining two outputs. In dual link mode, the 7751TG2-HD outputs a 4:4:4 test signal on two dual-link 4:4:4 outputs.
The 7751TG2-HD provides for an analog genlock input that allows you to synchronize the test signals to your plant horizontal and vertical timing. Separate audio tones can be embedded into each channel of the four embedded audio groups. The user can select which of the audio groups the tones will be embedded into. In dual link mode, the selected audio group can be embedded into either or both links. The audio level is fixed at -20dB full scale.
