The TG8000 is a precision multiformat analog and digital signal generation platform, designed for sync pulse and timecode generation in broadcasting applications and reference test signal generation in video equipment testing applications. It is a modular system, accommodating up to four user-changeable generator modules and one power supply module in a full-width 1RU form factor. A total of 12 different modules are available for the TG8000, covering a wide range of interfaces and functions such as GPS synchronization and genlock, SD/HD/3G-SDI test signal generation, composite and component analog test signal generation, and audio test signal generation. The TG8000 mainframe has a high-precision oscillator for master operation, or for stable holdover operation when the genlock or GPS reference is interrupted. A 10/100/1000BASE-T Ethernet interface provides connectivity to the local network for remote operation, test pattern download, and an NTP server (when the GPS7 module is present). A General Purpose Input/Output (GPIO) interface is available to recall one of seven user-configured presets and to report system alarms. The front-panel USB port can be used to easily download user-created test patterns and system preset information, and can be used for system upgrades.
