CBG830 High Definition Color Bar Generators


The CBG830 color bar and test signal generators will produce a quality, high definition full field color bar signal compatible with the digital HDMI and DVI-D interfaces. The CBG830 is designed to provide an accurate and affordable signal source for easy testing of displays, cables and systems.

The CBG830 will generate a full field color bar signal with eight vertical bars, white through black. This signal is available in a variety of resolutions and refresh rates. TheCBG830 will usually fit in a toolbox with ease and even fit into a pocket. There is also a rack mount kit available as well. Power is provided by a regulated 5VDC source and a small wall plug power module is included with the packaged CBG830 but not with board level products. The CBG830 will have a switch array to select the video standard.

The clock source inside the CBG830 is a precision, 2.5ppm tight tolerance stable source. This clock is used as the basis for all operating modes The output is via a standard HDMI connector and power is supplied through a 1.3mm coaxial power connector. Power is from a 5VDC @ 250mA, regulated power source (included with cased units but not with board level products).

The CBG830 series is available in two styles, packaged or board level. Board level products do not include the power supply and a 5VDC regulated power source must be provided. The standard board level product with a -01 suffix includes the standard video and power connectors that the cased product uses. For OEM applications, we can provide units with header and other connection types (except for video out). Custom designed or modified versions may also be available. MicroImage Video Systems has designed many custom derivatives of our standard color bar generator to meet special needs. We would be glad to help with your application. We can provide product at the chip level as well. Quantity discounts are available.

The CBG830 each have a one year parts and labor limited warranty. All units are RoHS compatible.
