Tektronix® SPG8000A
Master Sync/Master Clock Reference Generator
Available directly from Grass Valley for both IP and non-IP infrastructures, the Tektronix SPG8000A Master Sync/Master Clock Reference Generator (also available directly from Grass Valley) is used in a configuration consisting of two units with a single Tektronix ECO8000 Automatic Changeover Unit (also available directly from Grass Valley) for most broadcast facility, studio, mobile and post-production timing applications. It provides multiple video reference signals, such as blackburst, HD tri-level sync, and serial digital and composite analog test patterns. For IP installations, the combination of two or more SPG8000A units will support Precision Time Protocol (PTP) IEEE 1588...
FEATURES
- Multiple independent blackburst and HD tri-level sync outputs provide all the video reference signals required in a video broadcast or production facility
- Four LTC outputs, VITC on blackburst outputs, and NTP server provide time reference signals in a variety of formats
- PTP (IEEE 1588) support, including SMPTE ST 2059-2 and AES67 profiles
- GPS/GLONASS-based synchronization gives an accurate time-of-day reference and deterministic video phase reference across multiple independent systems
- Stay GenLock and Holdover Recovery prevent synchronization shock when the external reference input, PTP, or GPS/GLONASS signal is temporarily lost
- Wide selection of video test patterns in serial digital formats (SD, HD and 3G-SDI) and composite analog formats (NTSC and PAL)
- 4K UHD formats support with full frame 100% and 75% color bars (Quad Link Square Division)
- Dual hot-swappable power supplies ensure continuous availability of reference signals
- Easy to manage with Web-based interface for remote configuration and SNMP for status and alert information
