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.

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

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.

Ordering Information

When Ordering, Please Observe These 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) may be combined in any mix
desired up to the TG2000 mainframe limit of 8. The mainframe may
contain a maximum of 4 of any combination of HDVG1 and AWVG1
modules

Only one HDST1 module per TG2000 mainframe. Additional limitations
may apply, depe
configured with an HDST1. Contact Tektronix Technical Support for
details

The performance of the TG2000 is degraded to the E4 environment for
radiated emissions only when operating with a combination of HDVG
and HDST1 in HD-SDI stress testing applications

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