7751TG2-CF-HD
HD/SD-SDI Trouble Slide and Test Pattern Generator
The 7751TG2-CF-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-CF-HD is ideal for checking signal path integrity, or to determine system performance over varying cable lengths. The 7751TG2-CF-HD generates test signals in a wide variety of SMPTE 292M and SMPTE 259M video formats. In single link mode, the 7751TG2-CF-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-CF-HD outputs a 4:4:4 test signal on two dual-link 4:4:4 outputs. The 7751TG2-CF-HD provides an analog genlock input that allows you to synchronize the test signals to your plant horizontal and vertical timing.
The 7751TG2-CF-HD provides downloadable bitmaps for trouble or test slides. Customers may store their own designed bitmaps (trouble slides, test slides, or test signals) into a directory structure on the compact flash. The module allows users to output one trouble slide on a pair of outputs and another trouble slide on the second pair of outputs. The 7751TG2-CF-HD comes with a 128MB compact flash.
Separate audio tones or user created WAV files can be embedded into each channel of two 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 groups will be embedded into each link. The Audio level is fixed at -20dB full scale.
