Link Electronics SPG-812/SD SDI Master Sync Generator
Link Electronics SPG-812/SD SDI Master Sync Generator
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 accurateanalog and digital timing reference signals. A looka-like chassis is designed for the AutomaticChange-over unit. It's modular construction offersunmatched flexibility to the user, and provides aneasy means of upgrading from analog to digital.
The SPG-812 consists of a 1RU chassis andpower supply with six module cells toaccommodate various module functions. Onemodule cell is dedicated as a dual analog/digitalaudio reference tone generator. A digital only tonegenerator is also available. The second cell isdesignated as the master gen-lock module ormaster timebase unit. The selection of gen-lockcan be either analog or digital through a dedicatedmodule. The optional gen-lock module providesthe timebase signals for all chassis modules. Anyof the output modules may be installed in theremaining four cells. The four cells can be used inany of the four remaining cell for analogblackburst, component digital black, analogcomposite test pattern, component digital testpattern, source ID, ratings code monitor or captiondecoder. 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 threeoutputs per module and each module has its ownindependent infinite timing adjustments. A dualaudio tone generator is available to provide Silent,0dB, -10dB and -20dB levels.
The SPG-812's flexibility is unmatched in theindustry. Each module is accessible from the frontof the unit and may be easily installed or removed.All timing adjustments are located on the front cardedge. It is possible to begin with an all-analog unitand gradually upgrade to an all-digital unit simplyby combining the appropriate modules. If gen-lockcapability is not required, an output module maybe installed in the "gen-lock" slot to serve as theunit's master timebase. The digital and analog testgenerators may be plugged into the SPG-812 as astand-alone test signal generator without any otheroptional module as they equipped with it owntimebase.
