SPG-812/SA ANALOG MASTER GENERATOR
SPECIFICATIONS
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 hold
up 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 may
be 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.
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.
