Data Sheet
TG2000 configured to supply signals in several formats simultaneously.
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
16 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 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 can be used as a source of tri-level 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 SDP2000 PC-based
signal development software.
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 stressing options include Jitter (amplitude or frequency), amplitude,
duty cycle, and random error insertion. The HDVG1 is recommended as a
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
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 Reference Operation
The TG2000 has a high-stability internal reference making it suitable 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.
Remote Control
The TG2000 provides a versatile and comprehensive remote control
system. All front-panel functions and controls are available through the
RS-232 and optional GPIB ports. A subset of those functions is available
through ground closure control.
