NOTES:

1) AC Mains power must be turned off while removing or installing any module. Failure to do so
may cause damage to the mainframe and/or module. Such damage is not covered by the
product or service warranties.

2) All modules contain electrostatic sensitive components. Proper static prevention measures
must be followed while handling the modules.

3) The Main Module must always be used in the bottom most slot of the mainframe.

4) The Sync Module must always be used in the second slot from the bottom of the mainframe.

Proper Video Termination

Improper termination of the video outputs will result in degradation (ringing, undershoot and/or
overshoot) of the test signals. The following figures show suggested methods for connecting
the video generator to displays having 50 and 75 Ohm input impedances in both differential and
single ended modes of operation.

1) The firmware includes a library of over 100 standard video formats. This is a common library
shared by all our Model 801, 802 and 822 series video generators. As part of the factory
initialization of each unit, the firmware scans all of the library formats for compatibility with a
given model and hardware configuration. All compatible formats are added to the knob list.

2) The firmware includes a library of over 100 built-in test images (patterns). This is a common
library shared by all our Model 801, 802 and 822 series video generators. Some test images
may not be compatible with some video formats and hardware configurations. An on-screen
message indicates these patterns are not supported when they are selected.

3) User defined video formats and custom test images can be stored in the generator using
Quantum Data’s MS-Windows

® based VGM software.
