The Tektronix SPG8000 Master Sync/Master Clock Reference Generator is a precision multiformat video signal generator, suitable for master synchronization and reference applications. The Tektronix SPG8000 Reference Generator provides multiple video reference signals, such as black burst, HD tri-level sync, and serial digital and composite analog test patterns, and provides time reference signals such as time code and NTP (Network Time Protocol).
The base configuration of the Tektronix SPG-8000 includes three sync outputs that can be configured with independent output formats (NTSC/PAL black burst and/or HD tri-level sync) and independently adjustable timing offsets. With the BG option, four more analog outputs can be added. A high-accuracy, oven-controlled crystal oscillator provides a stable frequency reference for the system, or the pass-through genlock input can be used to lock to an external video reference or 10 MHz continuous wave signal. The Tektronix SPG 8000's Stay GenLock feature avoids "synchronization shock" if the external reference suffers a temporary disturbance, by maintaining the frequency and phase of each output signal. When the external reference is restored, Stay GenLock ensures that any accumulated clock drift is removed by slowly adjusting the system clock within standard limits instead of "jamming" back to the correct phase.
Time reference outputs are available in multiple formats. Three independent linear time code (LTC) outputs are available, and a fourth LTC connection can be used as input or output. Each LTC output has independent frame rate selection, time source (time-of-day or program time) and time zone offset. Vertical interval time code (VITC) is available on each NTSC or PAL black output, also with independent time sources and offsets. The Tektronix SPG/8000 can also serve as a Network Time Protocol (NTP) server, providing the time-of-day reference to network-attached devices.
