Tektronix Addresses Broadcasters Reference Generator Requirements with New SPG8000

SPG8000 Master Sync and Master Clock Reference Generator Brings New Level of Reliability to Modern Digital Video Facilities

Tektronix, the market leader in broadcast video test, monitoring and analysis solutions, today unveiled its SPG8000 Master Sync and Master Clock Reference Generator, an entirely new type of reference generator that combines Tektronix’ industry-leading sync pulse generator (SPG) and master clock reference generator capabilities specifically for HDTV production.

The SPG8000 sets a new standard in reference generators, providing the critical timing and synchronizing signals for modern broadcast, production (including mobile trucks and OB vans) and post-production facilities.  The new SPG8000 will be demonstrated at the Tektronix stand 10.D41 at IBC 2012 in Amsterdam.  The fully-featured SPG8000 comes standard with individually timeable black burst (with VITC support) and HDTV tri-level sync outputs, 10 MHz and 48 kHz word clock outputs, linear time code (LTC) outputs and network time protocol (NTP) server support. Optional capabilities include GPS synchronization, HD/SD-SDI signal generation (with ATC support) with an upgrade path for 3G-SDI signal generation (software upgrade), 8 channels AES/EBU audio signal generation plus digital audio reference signal (DARS) output, and analog NTSC/PAL color bar and test signals outputs.

In addition to combining extensive sync pulse generation and master clock reference generation capabilities in the single device, the SPG8000 incorporates several key features, including Tektronix’ Stay Genlock® capability, redundant power supplies and SNMP and Web UI support.


The SPG8000’s Stay Genlock capability addresses the requirement that modern digital video systems have for ultra-high stability and availability of synchronization and timing signal sources.  Specifically, Stay Genlock enables the SPG8000 to maintain the reference clock frequency and phase even when there is a loss of the genlock reference input signal. Additionally, the SPG8000 is the only solution of its kind that will gradually reacquire lock when the genlock signal is reapplied, minimizing disruption to devices synchronized to the SPG8000 reference signals and eliminating synchronization shock.

Given its vital role, the SPG8000 has been designed for maximum reliability.  It can be configured with dual, hot-swappable power supplies to ensure uninterrupted availability of its critical timing and synchronization signals. Should the primary power supply fail for any reason, the back-up supply will automatically engage to minimize any disruptions. To further ensure maximum reliability, the SPG8000 will periodically load test the backup power supply to verify that it can step in when required.


“The SPG8000 represents an entirely new product category for Tektronix. With the SPG8000 we are now providing customers with the most robust solution in its ability to eliminate any synchronization shock in a system, and by offering a redundant dual power supply which provides 24/7 non-stop operation – all together we are providing another level of assurance for minimum disruption in operation,” said Eben Jenkins, general manager, Video Product Line, Tektronix.  “This new product continues the Tektronix tradition, delivering the superior performance, innovation and attention to detail that broadcasters the world over expect from Tektronix.”

The SPG8000 can also be remotely configured and monitored, meeting a key requirement of broadcasters as they increasingly deploy automation and central monitoring and control systems in their facilities.  The SPG8000’s key features in this regard are its support for SNMP and the new Tektronix Web user interface, which enable easy integration into broadcasters’ monitoring and control systems.


The SPG8000 Master Sync and Master Clock Reference Generator is available globally for ordering today. For more information about the SPG8000 visit the Tektronix stand 10.D41 at IBC 2012
