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 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 for clock synchronization of IP-based broadcast equipment...

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
