The TG2000 is a multiformat, analog and digital,
precision signal generation platform. Designed for
the most demanding test applications, the TG2000
provides reference quality test signals, stressing func­tions in both the analog and digital domains, and the
flexibility to address user-defined testing require­ments. Comprehensive test signal libraries are
supplied in all formats and are supplemented by a
Windows-based test signal development program.
The modular architecture, RAM-based test signal gen­erators and programmable system clocks ensure the
TG2000 will meet future needs as well as today’s
requirements.

AVG1 ANALOG VIDEO GENERATOR

The AVG1 is a high accuracy, multiformat analog test
signal generator. The AVG1 supports NTSC, PAL,
PAL-D, PAL-M, PAL-N, SECAM, RGB, YC and Y, B-Y,
R-Y. Signal generation architecture is 12-Bit, 27 MHz
component with digital modulation for composite
signals. This ensures high accuracy, distortion free
signals within a 6 MHz video bandwidth and signals
suitable for many applications up to 8 MHz.

DVG1 DIGITAL VIDEO GENERATOR

The DVG1 is a multiformat digital test
signal generator. The DVG1 supports
NTSC composite and 525 and 625 compo­nent digital sampled at 13.5 and 18 MHz.
Parallel and serial outputs are provided.

Full field and active picture CRC genera­tion is supported on the serial digital
outputs and may be turned on and off
from the front panel. Up to four channels
of 20-Bit audio sampled at 48 kHz and
locked to the video sampling clock may be
embedded on the serial digital video
output. Frequency and level for each
channel may be set from the front panel.

AWVG1 ANALOG WIDE BAND VI DEO
GENERATOR

The AWVG1 is a 30 MHz bandwidth test
signal generator intended primarily for
generation of wide band frequency and
transient response test signals. The

AWVG1 can be used as a source of tri­level sync. Signal generation is 12 bits

with 72 MHz sampling that ensures very
low distortion T pulse generation for
bandwidths up to 6 MHz. A fully pro­grammable zone plate generator is
included. AWVG1 output is analog
composite.

HDVG1 DIGITAL HDTV GENERATOR

The HDVG1 is a high-accuracy, multi­format, high-definition test signal module
that provides three 1.485 Gb/s serial digi­tal video test signal outputs in 1080i/60,

59.94, 1080p/25 and 24 Hz rates and
720p formats in 60 and 59.94 field rates.
It is programmable with the included
SDF2000 PC-based signal development
software.

SDP2000 S IGNAL D EVELOPM ENT
PROGRAM

The SDP2000 is a Windows-based soft­ware program that provides facilities to
edit signals in the factory-supplied test
signal libraries and to create new signals
for special applications. Line and frame
editing functions permit fast, easy
changes to full field test signals and com­position of multi-segment matrix signals
for automated testing applications.
Modified and new signals may be named
and stored in the factory test signal
libraries or in new user-created libraries.

INTERNAL AND EXTERNAL R EFER ENCE
OPERATION

The TG2000 has a high stability internal
reference making it suitable as the master
house reference for most broadcast and
production/post-production applications.
A black burst output, selectable for NTSC
or PAL, is provided with the TG2000
mainframe.

REMOTE CONTRO L

The TG2000 provides a versatile and
comprehensive remote control system.
All front panel functions and controls are
available via the RS-232 and optional
GPIB ports. A subset of those functions is
available via ground closure control.

SIMPLE GUIDELINES:

• At least one signal generation module must accompany
each TG2000 mainframe

• Only one AGL1 Genlock Module per TG2000
mainframe

• Only one GP1 GPIB Interface Module per each
TG2000 mainframe

• Signal generator modules (AVG1, DVG1, AWVG1) may
be combined in any mix desired up to the TG2000
mainframe limit of 8. The mix may contain up to 4
HDVG1 modules

• Add Opt. 88 to each item ordered. This will ensure
your TG2000 package will come assembled and cali­brated as a single unit

• Modules ordered to add to an existing TG2000
