BEFORE OPERATING THE GENERATOR
Introduction
Thank you very much for purchasing this model VG-876 video signal generator.
This manual contains details on the operation procedures to be followed when the VG-876 is used, the checkpoints
and precautions to be observed, and so on. Improper handling may result in malfunctioning so before using the VG-
876, please read through these instructions to ensure that you will operate the generator correctly.
After reading through the manual, keep it in a safe place for future reference.
Safety precautions
WARNING
Concerning the generator
Do not subject the generator to impact or throw it. Doing so may cause the
generator to malfunction, explode or generate abnormally high levels of heat,
possibly resulting in a fire.
Do not use the generator where there is a danger of ignition or explosions.
Do not place the generator inside a microwave oven or other heating kitchen
appliance or inside a high pressure vessel. Doing so may heat up the generator to
abnormally high levels, cause smoking, running the risk of the generator’s catching
fire and/or damaging the circuit components.
This generator contains some high-voltage parts. If you touch them, you may
receive an electric shock and burn yourself so do not attempt to disassemble,
repair or remodel the generator.
If there is a thunderstorm while the generator is being used outdoors, immediately
turn off its power, disconnect the power cable from the main unit, and move the
generator to a safe place.
Concerning the power cord
Always take hold of the molded part of the plug when disconnecting the power
cord.
Do not use force to bend the power cord or bunch it up for use. Doing so may
cause a fire.
Do not place heavy objects on top of the power cord. Doing so may damage the
cord, causing a fire or electrical shock.
Concerning foreign matter
Do not spill liquids inside the generator or drop inflammable objects or metal parts
into it. Operating the generator under these conditions may cause a fire, electric
shocks and/or malfunctioning.

BEFORE OPERATING THE GENERATOR
xi
CAUTION
Concerning the generator
When connecting the generator to a display unit, use the FG cable provided to
connect the frame ground (FG) terminal on the generator to the frame ground
terminal on the display unit. If these terminals are not connected together, the
generator may fail. Take special care when connecting the generator to a display
unit which is under development.
When disconnecting the VG-876 from the display unit, first disconnects the
connecting cables, and then disconnects the FG cable.
When the generator’s power is to be turned ON or OFF, be absolutely sure to use
the POWER switch on the front panel. Turning the power on and off by plugging in
and unplugging the AC power cable may damage the USB memory.
Do not start using the generator straight away: instead, turn on the power of the
VG-876 and allow it to warm up for about 10 to 15 minutes before use so as to
ensure that the VG-876 will operate stably.
Never unscrew and open the cover on the side panel of the main unit while the main
unit power is turned on. Malfunctioning may result if the cover or the screw should
drop into the chassis of the main unit.
Concerning impact
This is a precision instrument and, as such, subjecting it to impact may cause
malfunctioning. Take special care when moving the generator.
Do not drop the generator.
Concerning installation
Install the generator in a stable location. Do not stand it on either of its side panels.
Doing so may cause the generator’s temperature to rise due to heat generation,
possibly resulting in malfunctioning.
When trouble or malfunctioning has occurred
In the unlikely event that trouble or malfunctioning should occur, disconnect the
generator’s power cable, and contact your dealer or an ASTRODESIGN sales
representative.

CONCERNING THE VG-876
1.1. General description
The VG-876 video signal generator supports applications in every field of display test and measuring.
It features a high level of expandability which is achieved by the installing video output interface units.
1.2. Features
16-bit high-speed imaging engine
This generator features a maximum 16-bit × RGB high-gradation imaging engine. It even draws
full HD images in an instant.
Wide dot clock frequency range
The VG-876 support a maximum dot clock frequency of 340MHz for digital outputs.
Windows-compatible editing and registration software (SP-8870) provided
as standard accessory
This software can be used to edit and register the program data and exercise control over the
signals output from the PC connected to the RS-232C/LAN/USB connector.
Full variety of sample data incorporated inside
A total of a thousand types of timing data and a thousand types of pattern data are registered
inside the VG-876 as sample data. They are categorized by standard, application and other
factors, and it is possible for the data required to be selected easily.
Registration of program data on USB memory
A total of a thousand program data can be registered on a USB memory. PC screens or natural
images can also be registered. On a PC equipped with a USB port, the data can be copied using
Explorer provided with Windows 98SE, Windows 2000, XP, Vista or 7.
Creation of user option patterns
In addition to the existing basic patterns (including character, crosshatch, color bar and gray
scale) and optional patterns, a function that allows users to create their own optional patterns has
been added. This function makes it possible to create the optional patterns which are useful for
developing and evaluating the next-generation displays.

1.3. Data configuration
The data output by the VG-876 is managed by the program data.
The program data consists of the pattern data which is used to set the data relating to the output images and the
timing data which is used to set the data relating to all other output timing data and output conditions.
The table below gives a breakdown of the data.
