GENFLEX SYNC GENERATOR SYSTEM
812-OP/E Analog and Digital Audio Generator (Mfr # 812OPE • B&H # LI812OPE)
The 812-OP/E produces a single AES/EBU digital audio signal for use as a digital audio reference or digital tone
source. It also produces a balanced stereo analog audio signal of up to +28dBu for use as a test tone. It offers
genlocking of the audio to digital or analog video within the frame. Or can be selected to free run with its
high stability oscillator. Amplitude and frequency of the audio tone can be set from a fixed set of 8 combinations,
including three frequencies (1KHz, 400Hz, 60Hz) and three levels (0dBFS, -10dBFS, -20dBFS). With this, it can produce “digital silence”
while producing one of the eight combinational tones on the output. There are two digital outputs and one analog output. Analog audio tone levels
can be adjusted in 2dB increments. LEDs are used to indicate tone frequency and level, digital silence, lock status, and power indication................514.95
SPG-812 Generator Chassis (Mfr # SPG812 • B&H # LISPG812)
The SPG-812’s flexibility is unmatched. 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 genlock capability isn’t required, an output module may be installed in the “genlock” 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. Includes power supply and motherboard.............................................................................................................................................................819.95
812-OP/A • 812-OP/B
Analog and Digital Blackburst Modules
The 812-OP/A uses three 2-bit mechanical encoders that give infinite
phasing on both the vertical,
horizontal, and subcarrier timing.
The 812-OP/B digital burst
module uses two 2-bit
mechanical encoders that give
infinite phasing on both the
vertical and horizontal timing.
This makes them ideal reference
generators, compensating for any timing offset within the timing chain.
Timing information is stored in RAM and can be held there if chassis
power is interrupted, or if you move the module from chassis to chassis.
They go in any slot. When placed in genlock slot #1 they become the
master and all other modules slave to it. They can’t genlock to external
video in the genlock slot. They can only run on its internal time base or
free-run mode. When in free-run mode, a front panel control adjusts the
frequency of the Voltage Controlled Crystal Oscillator (VCXO).

812-OP/C • 812-OP/D
Analog and Digital Genlock Modules
The 812-OP/C accepts analog black burst to genlock to an external
source. The 812-OP/D accepts
digital blackburst to genlock to an
external source. The genlock cell
is slot number two. Whether
module 812-OP/C or 812-OP/D, all
other modules lock to whatever
is in cell number two. The slot
two module will produce the
necessary lock pulses for all of the other modules in the chassis. The
remaining four cells will accept a digital or analog test of black module.
The 812-OP/C or 812-OP/D take in a stable analog or digital black burst
signal and genlock to it.
A video presence detector controls if the module is in genlock or free-run.
A bi-color LED is used for a video presence indicator. If there is no video,
they automatically switch over to a free-run frequency condition and a
front panel control is used to adjust the DC voltage of the VCXO.

Link’s GenFlex system provides accurate analog and digital timing reference signals. Modular construction offers unmatched
flexibility, and provides an easy way to upgrade from analog to digital. The system consists of a 1RU chassis and power supply
with six slots to accommodate various modules. One module slot is dedicated as a dual analog/digital audio reference tone
generator. A second slot is designed as the master genlock module (can be either analog or digital). The genlock module
provides the timebase for all chassis modules. Any of the output modules may be installed in the remaining slots. The output
modules are: analog blackburst, component digital black, analog test patterns, component digital test patterns, pulses (SY, SC
& BL) and digital audio (AES3-ID). There are three outputs per module and each module has its own independent infinite timing
adjustments. A dual audio generator is available to provide1KHz & 400 Hz reference tones and digital reference silence.
