    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 and control systems.
