Introduction
About this Manual
This manual discusses how to set up and operate the Extron VTG 400D/400 DVI
programmable video test generator.
Throughout this manual the terms “VTG”, “video test generator”, and
“VTG 400D/400 DVI” are used interchangeably to refer to the same products.
About the VTG 400D/400 DVI
The Extron VTG 400D and VTG 400 DVI 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 400D/400 DVI 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. A DVI-D output is included with the
VTG 400 DVI.
The VTG is designed to provide a wide variety of reference signal types. A total
of 113 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.
A powerful and innovative feature is the Scope-Trigger
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. DVI-D (VTG 400 DVI) is output via a DVI-I 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 (except the VTG 400 DVI) 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 can be remotely controlled by a host
computer via an RS-232 control port utilizing Extron’s Simple Instruction
Set (SIS
control software.

response of audio systems.
• The burst interval is defined by the total number of cycles
(on and off) in each repeating period.
• The burst on duration is defined by the number of cycles
in the interval where the sine wave is turned on.
See the burst signal example below.
Random noise that has constant energy per octave.
Used in loudspeaker testing and calibration.
Random noise that has an equal energy distribution
across all frequencies between 20 Hz and 20 kHz.
Used in detecting distortion. The frequency can be set
