SPG800A Master sync

Tektronix SPG8000A multiformat video signal 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 black burst, HD tri-level sync, and serial digital and composite analog test patterns, and it provides time reference signals such as time code, NTP (Network Time Protocol), and IEEE 1588 PTP (Precision Time Protocol).


Key features

The SPG8000A is a precision multiformat video signal generator, suitable for master synchronization and reference applications.

  • 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
  • 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


  • Sync generator and time reference generator for broadcast, studio, mobile, and post-production facilities
  • Master or slave (genlock) operation for distributed system architectures
  • Video equipment verification, facility link testing, and display calibration

Designed for Mission Critical Sync System Reliability

The SPG8000A and ECO8000 are designed with one mission in mind: the provision of a stable, reliable, and accurate timing reference under any conditions. It’s the detail that is paramount in mission-critical systems; redundant power supplies, the patented Stay Genlock and Holdover Recovery algorithms, and full PTP BMCA algorithm support, coupled with the electronic switching capability of the ECO8000. This earns the title ‘Best in Class’ as a master reference signal failover system.


  • Stay Genlock™ and Holdover Recovery bridges the loss of GPS or External Reference
  • Full support for the ST2059 BMCA algorithm and GPS lock for high reliability PTP Grandmaster
  • Both SPG and ECO employ unique dual hot swappable power supply design with sophisticated monitoring
  • The SPG complemented by the electronic switching capability of the ECO8000, minimizes shocks to analogue reference signals
