AGL7 Analog

Genlock Module.

The TG700 is a multiformat, analog and digital, precision signal generation
platform. Designed with the changing needs of the video industry in mind,
the TG700 offers sync pulse generation and test sign al generation for a
wide array of analog, serial digital, and digital high-definition formats. The
TG700 Mult

iformat Video Generator has a modular architecture that offers
the flexibility to meet the single-format and growing multiformat needs of the
video professional. The TG700 mainframe allows up to four of the following
modules to be fitted in the mainframe.

The TG700 has a high stability reference. The AGL7 Analog Genlock
Module adds the capacity to lock to a variety of signals, which makes the
TG700 an ideal solution as the master house reference or s lave reference
for broadcast and production/post-production applica tions. Three black
outputs a

re available and are selectable for HDTV tri-level or NTSC or PAL.
Additionally, the AGL7 can lock to a variety of formats to include NTSC/PAL
black and HDTV tri-level as well as 1, 3.58, 4.43, 5, and 10 MHz CW. When
theAGL7isconfigured for Stay GenLock™ mode, a momentary loss of
synchronization at the genlock reference input will not cause a disturbance
in the TG700’s test signal and black outputs. When the genlock signal is

d, the AGL7 will gradually reacquire lock, causing little disruption to

reapplie
devices synchronized to the TG700 reference.

The GPS7 G

PS Synchronization and Time Code Module includes an
integrated GPS receiver which can serve as the system timing reference.
Synchronization to the GPS timing signals ensures long-term st ability,
and video frame alignment between indepe ndent systems. The GPS RF
coaxial signal input is available with 3.3 V or 5 V DC power output for the
GPS antenna enabling the user to select from a variety of GPS antennas

le on the market. The GPS7 also includes a genlock input with

availab
VITC reader, enabling user-selectable c onfiguration of the TG700 as
the master reference or as a slave to another master, depending on the

dynamic requirements of each production. The GPS7 module will maintain
system timing by Stay GenLock™ technology even during periods of GPS
signal loss or genlock signal loss. Three black outputs are available and
are selectable for HDTV tri-level, NTSC, or PAL. Time code source can
be selectable to the time-of-day (with user-selectable offsets) from GPS
receiver, internal source, VITC on the reference input, LTC inpu t, or to a
"program time" counter for elapsed-time time code. The Daylight Savings
Time (DST) adjustment could be recurring scheduled, based on calendar
rules. Time code is available as VITC on black outputs (GPS7, BG7), as
Ancillary Time Code (ATC) (HDVG7, HD3G7, SDI7), from four independent
LTC outputs (GPS7), and as a response to time requests on a Simple
Network Time Protocol (SNTP version 3.0) Server.

The ATG7 Composite Analog Test Generator supports PAL, NTSC, and
NTSC No Se

tup. It provides one test signal output, one color bar test
signal output, and two black outputs. The black outputs can independently
generate H, V, black burst, and subcarrier.

available.

The HDVG7 is a high-a c curacy, multiformat, high-definition test signal
module that provides up to two identical 1.485 Gb/s serial digital video test
signal outputs in a broad variety of formats. With Opt ion BK, two additional
identical serial black signal outputs are available. Ancillary Time Code
(ATC) generation is available when the GPS7 is installed in the TG700
mainframe. Up to t wo HDVG7 modules can be placed in a single TG700
mainframe.

The digital modules DVG7 and HDVG7 support AV timing mode and up to
