SPG700 Datasheet

Multiformat Reference Sync Generator

Читать на веб-сайте:

The SPG700 is a multiformat reference sync generator with optional 3G/⁠HD/⁠SD-SDI test signal generator support for traditional SDI-based video infrastructure. It provides multiple video reference signals, such as black burst and HD tri-level sync, and audio reference signals, such as DARS and 48 kHz word clock, and it supports various timecode formats for time reference generator applications.

Key features
  • Multiple independent black burst and HD tri-level sync outputs provide all the video reference signals, while DARS and 48 kHz word clock 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
  • Wide selection of video test patterns in serial digital formats (SD, HD and 3G-SDI)
  • 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
Applications
  • Sync generator and time reference generator for broadcast, studio, mobile, and post-production facilities
  • Video equipment verification, facility link testing, and display calibration

Sync generator and time reference generator

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 offsets.

Test signal outputs

The SPG700 can be optionally configured with a variety of test signal outputs.

Option SDI adds two fully independent serial digital video generator channels of two outputs each. Each channel can be configured to any standard 3G/HD/SD-SDI format and frame rate. The selected test pattern can be generated on both outputs per channel, or one output can generate digital black.

A wide variety of standard test patterns are included, such as color bars, convergence grid, step scales, ramps, multiburst, SDI pathological test matrix and a real-time programmable zone plate generator. Bitmap images can be downloaded to the SPG700’s flash memory for arbitrary user defined test patterns. ID text, burn-in time code, circle, and color logo overlays can be added to any test pattern, and several ancillary data packet types, including ancillary time code and user-defined packets, can be inserted into the SDI output signal.

The four SDI outputs can be configured to support 4K/UHD full frame, 100% and 75% color bars for quad link square division mode. This allows simple verification of your 4K/UHD workflow within the production studio or mobile truck. Note: VPIDs are compliant only to HD and 3G formats in 4K/⁠UHD formats.

Also included is an audio/video delay test sequence, which in conjunction with a Tektronix waveform monitor, can be used to ensure A/V delay compliance.

Audio reference signals

Audio reference signals are available on the SPG700. The base configuration includes a 48 kHz word clock output and a Digital Audio Reference Signal (DARS) output.

Audio tone generation is also included with Option SDI as embedded audio on each of the SDI outputs.

Remote access

The SPG700 includes a 10/100/1000BASE-T Ethernet interface for remote access to the instrument. A web-based user interface can be used for all configuration settings and for monitoring system status.

Alarm and key status information is also available via Simple Network Management Protocol (SNMP) messaging, enabling easy integration with network management systems. Remote control and alarm reporting is also available via a general purpose interface (GPI).

The SPG700 has a front-panel USB port that can be used to backup and restore presets and other user data, and to perform system firmware upgrades.

Optional backup power supply

For mission-critical applications, the SPG700 can be configured with a second power supply module. Under normal operation, the designated backup supply is seldom used, ensuring that it has maximum remaining life should the primary supply fail. The backup supply is load-tested once each day to verify that it can serve as the primary supply if necessary.

The usage time of each supply is logged as “temperature-weighted hours”, a metric that best estimates the calculated life of the supply. A front-panel LED will indicate when the supply is nearing its end-of-life.

If the primary supply is interrupted for any reason, the system will switch to the backup without any disruption to system operation. Power supply modules are hot-swappable for easy replacement, and feature a locking mechanism to prevent the power cable from accidental disconnection.
