7750TG-TS
Transport Stream Generator
The 7750TG-TS Test Signal Generator provides a cost-effective method of generating SMPTE 310M and ASI test signals. The 7750TG-TS is ideal for checking signal path integrity or to determine system performance over varying cable lengths. The 7750TG-TS generates test signals in either SMPTE 310M or DVB-ASI transport stream formats.
The 7750TG-TS provides an analog genlock input that allows you to synchronize the test signals to your plant horizontal and vertical timing.
Features
- SMPTE 310M and ASI outputs
- ATSC and MPEG-2 Main Level Main Profile structures
- Multiple bit rates in ASI output mode
- Multiple video test signals, motion and non-motion, each is a fixed loop of GOPs
- All appropriate tables for ATSC and DVB supported
- Genlocks to bi-level or colour black - clock or phase lock possible
|
- Card edge toggle switch selects test signal
- On-screen setup menu
- Composite analog output with on screen menu display on gray
- 8 position DIP switch selects output format
- Two output drivers
- Tally output upon loss of gen lock
- Card edge LEDs indicate gen lock presence, and module status
