Introduction Introduction Introduction VTG 150 Features 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.

Connecting the VTG Output Cables Connecting the VTG Output Cables 100-240 VAC VTG 200 ↑ VTG 150 ↓ The VTG 200 (above) provides six sets of video output connectors; the VTG 150 (at right) provides four sets. Each connector is marked for its video application. Connecting the VTG Output Cables 15-Pin Apple/Mac II (VTG 150), MacII/Quadra (VTG 200) Output All scan rate signals go to the VGA/ XGA (15-pin HD), Apple/MacII/ Quadra (15-pin) and BNC connectors.
Connecting the VTG Output Cables Connecting the VTG Output Cables RGB Output (BNC, Analog) The RGB BNC output provides red, green, and blue video at 0.7 volts peak to peak and horizontal and vertical sync at TTL levels on the H/HV and V BNC connectors.
Connecting the VTG Output Cables Connecting TTL Output to an AT&T 6300 When using the VTG 150 TTL output with an AT&T 6300 monitor, an adapter cable is needed with the following configuration: 9-pin Signal 25-Pin 1 Ground 14 & 15 3 Red 4 4 Green 5 5 Blue 6 6 Intensity 7 8 H Sync 1 9 V Sync 3 Extron VTG 150 & VTG 200 User’s Manual 3 Chapter Three Operating the Video Test Generator Operating the Video Test Generator Page 2-5 Extron • VTG 150 & VTG 200 • User’s Manual
Operating the Video Test Generator Operating the Video Test Generator Operating the Video Test Generator Connect the video test generator to the device to be tested. (See Connecting the VTG Output Cables in chapter 2.) Exit the Instructional Menu Cycle To exit the instructional menu cycle, press the ▼ or ▲ button. A scan range will be displayed on the LCD screen. View the Scan Ranges To view the available scan ranges (i.e. TTL, VGA, Mac), hold the MODE/ON button down and press the ▼ or ▲ button.
Operating the Video Test Generator Operating the Video Test Generator Unless it is disabled, the timer will begin its countdown to time-out when the Timer LED turns green (indicating that a single test pattern is being displayed). The countdown restarts each time any button is pressed. _ When a time-out occurs, only the video display will be cut off; the sync will remain active, even while the video is muted, thus convergence settings will not be lost.

Application Information 150# 200# Format IBM Power PC, cont’d VTG Formats The table below lists the formats in the order in which they appear on the LCD screen when using the ▲ button to step through the choices. Use the ▼ button to go backward. To skip from one “range” or set of scan rates to the next, hold the MODE button while pressing ▼ or ▲ . The columns labeled 150# and 200# are the format numbers for the VTG 150 and the VTG 200.
Application Information Video Test Patterns The following is a listing of the available test patterns and a brief description of the purpose of each. Pattern 1 — Dots 12 x 16 - Focus and Convergence This pattern is effective for checking and adjusting focus and convergence. Pattern 2 — Alternating Pixels - Resolution This one pixel on, one pixel off pattern is used to test display resolution of monitors and projectors as well as EMI testing for worst case radiation.
Application Information Setting Up Large Screen Projection Systems Application Information Video Setup Guide The video test generator may be used to set the parameters of large screen video/data projectors. These parameters include convergence, geometry, linearity, grayscale, contrast, brightness and focus. For each application, a digital projector requires a separate set of signals from each computer/video source.
Application Information Application Information Monitor Applications The VTG can be used in a variety of monitor testing and adjustment applications using the 16 available test patterns. Following is a brief summary of some of the uses in these types of applications. • Color convergence or registration can be done using any of the crosshatch or dot patterns. (See figures 4-8A & 4-8B.
Application Information Application Information Troubleshooting The VTG 150 or the VTG 200 can be used to help isolate problems within complex switcher configurations such as the one pictured below. The VTG can be used for presentation system troubleshooting. It can be placed in any part of the system to simulate a computer signal.

Duplicate most VTG 200 panel operations. Each VTG 200 ships with a 3.5” diskette containing the Extron Windows-compatible VTG 200 Control Program which enables the user to perform all of the above operations in a Windows environment. The program will be covered later in this chapter.
