상세보기:

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.

Key features
  • Multiformat analog and digital test signal generation
  • Ideal channel configuration and performance to support reference generator needs
  • Modular configurable platform
  • Stay GenLock™ – Unique, robust Genlock mode provides stable synchronization signals for digital and traditional broadcast facilities
Applications
  • Sync pulse generator and test signal generator for post production and broadcast facilities
  • Test signal generator for research and development
  • Equipment design and maintenance

TG8000 mainframe

The TG8000 mainframe 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.

AGL7 Analog Genlock Module

The AGL7 Analog Genlock Module adds the capacity to lock to a variety of signals, which makes the TG8000 an ideal solution as the master house reference or slave reference for broadcast and production/post-production applications. Three black outputs are available and are selectable for HDTV tri-level or NTSC or PAL. Additionally, the AGL7 can lock to a variety of formats to include NTSC/PAL black and HDTV tri-level as well as 1, 3.58, 4.43, 5, and 10 MHz CW.

When the AGL7 is configured for Stay GenLock™ mode, a momentary loss of synchronization at the genlock reference input will not cause a disturbance in the TG8000 test signal and black outputs. When the genlock signal is reapplied, the AGL7 will gradually reacquire lock, causing little disruption to devices synchronized to the TG8000 reference.

GPS7 GPS Synchronization and Time Code Module

The GPS7 GPS Synchronization and Time Code Module includes an integrated GPS receiver which can serve as the system timing reference. Synchronization to the GPS timing signals ensures long-term stability, and video frame alignment between independent systems.

The GPS RF coaxial signal input is available with 3.3 V or 5 V DC power output for the GPS antenna enabling the user to select from a variety of GPS antennas available on the market. The GPS7 also includes a genlock input with VITC reader, enabling user-selectable configuration of the TG8000 as the master reference or as a slave to another master, depending on the dynamic requirements of each production.

The GPS7 module will maintain system timing by Stay GenLock™ technology even during periods of GPS signal loss or genlock signal loss. Three black outputs are available and are selectable for HDTV tri-level, NTSC, or PAL. Time code source can be selectable to the time-of-day (with user-selectable offsets) from GPS receiver, internal source, VITC on the reference input, LTC input, or to a "program time" counter for elapsed-time time code.

The Daylight Savings Time (DST) adjustment could be scheduled as a recurring event based on calendar rules. Time code is available as VITC on black outputs (GPS7, BG7 – hardware V1.2 or above), as Ancillary Time Code (ATC) (HDVG7 – hardware V2.0 or above, HD3G7, SDI7), from four independent LTC outputs (GPS7), and as a response to time requests on a Network Time Protocol (NTP version 3.0) Server.
