    The SPG8000 is a precision multiformat video signal generator, suitable for master synchronization and reference applications. It provides multiple video reference signals, such as black burst, HD tri-level sync, and serial digital and composite analog test patterns, and it provides time reference signals such as time code and NTP (Network Time Protocol).

    The GPS option adds an internal receiver to the SPG8000 that is capableof receiving both GPS and GLONASS signals. When connected to an external antenna that supplies the standard GPS and/or GLONASS RF signal (for example, SPG8000ANT), the SPG8000 can use the GPS/GLONASS system's stable frequency reference.

    The GPS/GLONASS signal also includes a precise time-of-day reference that can be used for all time code outputs. Similar to the Stay GenLock feature, the SPG8000 can maintain the video frequency and phase when the GPS/GLONASS signal is interrupted, and the Holdover Recovery mode will ensure a shock-free realignment of frequency and phase when the GPS/GLONASS signal is restored.

    • Features

      • Multiple independent black burst 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 black burst outputs, and NTP server provide time reference signals in a variety of formats.
      • GPS/GLONASS-based synchronization gives an accurate time-of-day reference and deterministic video phase reference, and locks remote SPG8000 systems to each other.
      • Stay GenLock and GPS Holdover Recovery prevent synchronization shock when the external reference input 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).
      • 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.
