Tektronix SPG8000A
Master Sync/Master Clock Reference Generator.
The SPG8000A is a precision multiformat video signal generator, suitable for master synchronization and reference applications. It provides
multiple video reference signals, such as blackburst, HD tri-level sync,
and serial digital and composite analog test patterns, and it provides time
reference signals such as timecode, NTP (Network Time Protocol) and
IEEE 1588 Precision Time Protocol (PTP).
