SPG-812/SD SDI MASTERER GENERATOR
SPECIFICATIONS
Link's SPG-812 is designed to provide accurate
analoganddigitaltimingreferencesignals.Alook-
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, ratingscode monitororcaption
decoder.The812-OP/JsourceIDmodulewillhold
up to 32 pages of data and is RS-232 controlled.
Eachoutputmoduleisavailablefor525/60(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. Eachmoduleisaccessible fromthefront

Alltimingadjustmentsarelocatedonthefrontcard
edge. It is possible to begin with an all-analog unit
and gradually upgrade to an all-digital unit simply
bycombiningtheappropriatemodules. Ifgen-lock
capability is not required, an output module may
be installed in the "gen-lock" slot to serve as the
unit'smaster timebase. Thedigitaland analog test
generatorsmay be pluggedinto theSPG-812 asa

optional module as they equipped with it own
timebase.
The PCO-818 automatic pulse change-over
modules operate as independent or synchronized
operation. Two PCO-818 change-over chassis
may be interlinked to cause all modules to switch
should a failure occur in the master generator.
