AVG1 Analog Video Generator
The AVG1 is a high-accuracy, multiformat analog test signal generator. The
AVG1 supports NTSC, PAL, PAL-D, PAL-M, PALY, 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 a re 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
16 channels of 20-bit audio sampled at 48 kHz and locked to the video
sampling c lock may be embedded on th e serial digital video output.
Frequency and level for
each channel may be set from the front panel.

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 p rovides three 1.485 Gb/s serial digital video test signal outputs

HDST1 Stress Test Module
The HDST1 is a HD-SDI Stress Test module that supports stress test
capability for 1.485 and 1.485/1,001 Gb/s HD-SDI signals. The HDST1
takes in a single HD-SDI signal and outputs a stressed HD-SDI signal. HD
signals from test signal generators (including the HDVG1 module), as well
as from HD cameras, VTRs, or switchers, can be used as the input signal.

signal source, since it is capable of providing a signal with low residual Jitter,
as well as the ability to incorporate its frequency offset stress feature.

SDP2000 Signal Development 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 multisegment

Internal and External Reference Operation
The TG2000 has a high-sta bility internal reference making it su itable as the
master house reference for most broadcast and production/postproduction
applications. A black-burst output, selectable for NTSC or PAL, is provided
with the TG2000 mainframe.
AWVG1 Analog Wideband Video Generator
The AWVG1 is a 30 MHz bandwidth test signal generator intended primarily
for generation of wideband frequency and transient response test signals.
The AWVG1 ca n be used as a source of tri-level sync. Signal generation
