Link's SPG-812/SD is an SDI master sync generator, including: SPG-812 chassis & power supply, SDI genlock 812-OP/D, SDI black burst 812-OP/B, SDI pattern generator 812-OP/F, and AES + analog tone 812-OP/E.
Link's SPG-812 is designed to provide accurate analog and digital timing reference signals. A look a-like chassis is designed for the Automatic Change-over unit. It's modular construction offers unmatched flexibility to the user, and provides an easy means of upgrading from analog to digital.
The SPG-812 consists of a 1RU chassis and power supply with six module cells to accommodate various module functions. One module cell is dedicated as a dual analog/digital audio reference tone generator. A digital only tone generator is also available. The second cell is designated as the master gen-lock module or master timebase unit. The selection of gen-lock can be either analog or digital through a dedicated module. The optional gen-lock module provides the timebase signals for all chassis modules. Any of the output modules may be installed in the remaining four cells. The four cells can be used in any of the four remaining cell for analog blackburst, component digital black, analog composite test pattern, component digital test pattern, source ID, ratings code monitor or caption decoder. The 812-OP/J source ID module will holdup to 32 pages of data and is RS-232 controlled.
Each output module is available for 525/60 (NTSC)or 625/50 (PAL) operation. There are three outputs per module and each module has its own independent infinite timing adjustments. A dual audio tone generator is available to provide Silent,0dB, -10dB and -20dB levels.
The SPG-812's flexibility is unmatched in the industry. Each module is accessible from the front of the unit and may be easily installed or removed.All timing adjustments are located on the front card edge. It is possible to begin with an all-analog unit and gradually upgrade to an all-digital unit simply by combining the appropriate modules. If gen-lock capability is not required, an output module maybe installed in the "gen-lock" slot to serve as the unit's master timebase. The digital and analog test generators may be plugged into the SPG-812 as a stand-alone test signal generator without any other optional module as they equipped with it own timebase.
