The Tektronix SPG300, SD Sync Generator - Half Rack provides synchronization and test signals for both traditional analog and mixed digital and analog facilities, in both NTSC/525 and PAL/625 environments. These products are ideal as a stable master sync signal, which is critical in digital broadcast environments. When the SPG300 is configured for Stay GenLock mode, a momentary loss of synchronization at the genlock reference input will not cause a disturbance in the units test signal and black outputs. When the genlock signal is reapplied the SPG system will gradually reacquire lock, causing little disruption in the outputs of the device, and will not cause any noticeable glitches in the outputs of the SPG. The GEN lock source can be NTSC/PAL Black Burst, NTSC/PAL Sync or CW. When using CW lock, the GEN lock timing can be adjusted on all the NTSC or PAL color frames.

Analog Black Burst/Test Signal Outputs

The SPG300 provide four Black Burst output channels which may be independently timed over the full NTSC or PAL color frame range. The Black Burst output channels can be configured as a Black Burst or a Test Signal output, providing outstanding flexibility to handle your production facilities needs. In analog-to-digital transition environments especially, the sync generator needs to provide a variety of sync outputs. The SPG300 is suitable for use as a master sync generator for small facilities or as a slave sync generator in larger environments.

The SPG300 also provides basic test signals for analog facilities. These test signal outputs can include ID text (up to 20 characters) or Logo insertion. The ID Text or Logo may be positioned anywhere in the viewable area and, if desired, be made to blink.

Serial Digital Video Outputs

The SPG300 provides two independently timed SD SDI Black outputs with full frame range for 525/60 or 625/50. The SD SDI Black output channel can be configured to provide SD SDI Black or SD SDI Test Signals, similar to the analog Black Burst outputs.

The SPG300 also provides fundamental test signals for digital broadcast environments, which are selected individually from the analog test signals. As with the analog outputs, up to 20 characters of ID Text or your Logo can be inserted into the signal, positioned anywhere in the image, and, if desired, set to blink.

There are 16 channels of embedded audio which can be active in the SD SDI outputs. Audio Click (1s, 2s, 3s, and 4s) is available for easy channel identification.

AES/EBU Digital Audio Outputs

Frequency and level can be set on the eight AES/EBU unbalanced outputs, and each channel can have separate Audio Click channel identification. The two XLR balanced outputs can be set up to match the 1+2 and 3+4 BNC outputs. One Word clock output is available.

Analog Audio Outputs

The default setting for the two XLR outputs is AES/EBU Digital audio. For analog audio applications, these two XLR outputs can be configured as two Analog Audio outputs. Frequency, level and audio identification can be set on each channel.

The SPG300 provides two XLR connectors for AES/EBU Digital Audio, and provides a one Word clock output.

SNMP and Web Remote Control

The SPG300 supports SNMP, making it easy to integrate these generators into automated service and maintenance functions. The Java applet based remote control makes it easy to remotely control these generators, and the remote monitoring software gives you a view of SPG300 operation at a distance. The SPG300 also provides traditional GPI features for reporting alarms and recalling presets.
