Product description The SPG700 Multiformat Reference Sync Generator from Tektronix provides multiple video reference signals, such as black burst and HD tri-level sync, audio reference signals such as DARS and 48 kHz wordclock, and it supports various timecode formats for time reference generator applications.The base configuration 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. 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 SPG700’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 offset. - General Features
-
- Multiple independent black burst and HD tri-level sync outputs provide all the video reference signals, while DARS and 48 kHz wordclock provide all the audio reference signals required in a broadcast or production facility
- Four LTC outputs and VITC on black burst outputs provide time reference signals in a variety of formats
- Stay GenLock prevents synchronization shock when the external reference input is temporarily lost
- 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
