Page 7: Overview
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. -
Page 8: Figure 1-1: 7751Tg2-Hd Block Diagram
From this point forward, the 7751TG2-HD and the 7751TG2-CF-HD modules will be referred to as the “7751TG2-HD”, unless the feature in question is applicable only to one of the modules, in which case the specific model number will be referenced. -
Page 9: Installation
7751TG2-HD Dual HD-SDI Test Signal Generator with Embedded Audio INSTALLATION The 7751TG2-HD module comes with a companion rear plate that has 5 BNC connectors. For information on mounting the rear plate and inserting the module into the frame see section 3 of the 7700FR chapter. - Page 10 SMPTE 259M. DIP switches 1 to 5 select the video standard (refer to Table 5-2). When the 7751TG2-HD is operating the 4:2:2 mode, these outputs contain the test signal. When the 7751TG2-HD is operating the 4:4:4 mode, these outputs contain...
