displays a series of instructional menus.
• Output connectors provide connection to RGB (BNC), TTL,
Macintosh and VGA/XGA devices.
• Sync output can be composite H/V; separate H & V; Sync on
Green; or sync on red, green, and blue.
• Automatic time-out to prevent video burn-in
• Pre-loaded scan rates - The VTG 150 has been pre-loaded
with the most popular video scan rates.
• Sixteen test patterns with selectable color combination
• Upgrades and options - As new scan formats are introduced,
the VTG 150 can be sent to Extron to be upgraded.
• Automatic test pattern sequencing for burn-in applications of
display and video processing equipment.

The VTG 200 Video Test Generator has all of the features of
the VTG 150 listed above plus:
• 13W3 output connector for Sun, SGI, IBM Power PC and
NEXT type monitors
• NTSC/PAL BNC output connector
• SMPTE color bar and PLUGE test pattern for NTSC/PAL
• RS-232 connector supports VTG 200 control and field
loading of scan rates (Extron or user-supplied scan rates).
• Internal power supply operates on any AC line voltage input in
the 100-240VAC, 50/60Hz range.

Introduction

Introduction

The Extron VTG 150 and VTG 200 Video Test Generators
reproduce computer video signals with patterns for testing
and repairing computer monitors, LCD panels, interfaces and
large screen displays. They are also used to setup and
simulate computer video for system installations.
Both the VTG 150 and the
VTG 200 have 16 selectable
test patterns for setting and
testing geometry, focus,
convergence, gray scale and
other parameters. After a test
pattern has been selected, the
color of each pattern may be
changed to display in the
colors white, black, red, green,
blue, cyan, magenta and
yellow.
The VTG 200 is field programmable through its RS-232 port.
New scan rates can be added by the user as they are
encountered on new equipment. The included Windows-
compatible software simplifies the programming.
This user’s manual provides the information necessary to
operate the VTG 150 and VTG 200 video test generators. A
label on the bottom of each unit provides quick-reference
operating instructions.
