Introduction
About this Manual
This manual discusses how to set up and operate the Extron VTG 400/400D
programmable video test generator.

“VTG 400/400D” are used interchangeably to refer to the same product.
About the VTG 400/400D
The Extron VTG 400 and VTG 400D are advanced, programmable, and
upgradeable video and audio test generators that deliver accurate, wide
bandwidth video signals and high performance audio test signals. These test
generators are professional quality reference tools for setup, performance
evaluation, calibration, and troubleshooting audio and video systems.
The VTG 400 offers a comprehensive array of video test patterns, as well as a
suite of audio reference signals. Video is output simultaneously as RGB,
component video, S-video, and composite video. An SDI and HDSDI output is
included with the VTG 400D. Audio is output simultaneously on a 3.5 mm mini
phone plug (unbalanced left and right mono) as well as on an RCA jack
(unbalanced mono) and a 3-pin XLR connector (balanced mono).
The VTG 400 is designed to provide a wide variety of reference signal types. A
total of 98 output scan rates are available for high resolution computer video, as
well as HDTV, NTSC, and PAL. Up to 183 additional rates can be programmed
into the VTG 400.
Operation of the VTG 400 is intuitive and convenient, with an easy-to-read LCD
screen on the main panel, direct access buttons, and memory presets for quick
saving and recall of user settings.
A powerful and innovative feature is the Scope-Trigger
™
output (patent pending),
which enables analysis of a selected area within the video image using an
oscilloscope. Scope-Trigger greatly simplifies and speeds up oscilloscope
setup for video signals by using a specially generated trigger signal precisely
timed to a user-defined target location on the image.
Other Features
Video output connectors — RGB, composite, and component video are output
via BNC connectors or a 15-pin HD connector (RGB). S-video is output
from a 4-pin mini DIN connector. SDI/HDSDI (VTG 400D) is output via a
BNC connector.
Audio output connectors — Audio outputs are via a 3-pin XLR connector for
balanced audio, a 3.5 mm phone jack for unbalanced left and right audio,
and an RCA jack for unbalanced audio.
Scope-Trigger cursor — The Scope-Trigger cursor may be visible or invisible. If
visible, the cursor may be either a crosshair or single pixel and can be
positioned anywhere within the video signal using the directional cursor
buttons.
RS-232 remote control — The VTG 400/400D can be remotely controlled by a
host computer via an RS-232 control port utilizing Extron’s Simple
Instruction Set (SIS
™
) of basic ASCII commands or through the Windows
®
-
based control software.
Flash-upgradeable firmware — The VTG’s firmware can be updated using the
Windows-based Control program via the RS-232 port.
Nonvolatile memory — The VTG 400 retains its configuration settings after the
video test generator has been powered off.
