CBG462 RGB Color Bar Generator


Only 3 left in stock (can be backordered)

SKU: CBG362-1-1 Categories: ,


The CBG462 series of color bar and test signal generator build on the standard set by our popular CBG410, CBG450 and CBG460 series with additional features and similar cost. The CBG462 unit will replace the CBG410F, CBG410S and CBG460 units.

The CBG462 is designed to provide an accurate and affordable signal source for system testing. It also provides the necessary components for aligning color monitors to the proper brightness, color and hue.

The CBG462 will generate a SMPTE style, split field color bar signal or a full field 100% white signal. The split field signal consists of the seven standard 75% bars including the left most gray bar in the top portion. Below this line is a small row of reverse bars that includes only those colors that have blue in them. This is primarily used for monitor chroma and phase adjustments. The bottom row consists of the standard -I, White, Q, Black and Pluge components. The Pluge signals make it very easy to properly adjust black level (brightness) on a video monitor.

The CBG462 will usually fit in a toolbox with ease and even fit into a pocket. A rack mount kit is also available. Power is provided by a regulated 12VDC source and a small wall plug power module is included with the packaged CBG462 but not with board level products.

The CBG462 operates with both NTSC (RS170) and PAL (CCIR) video systems, an internal switch selects the video standard. The CBG462 series generate standard RGB or YUV signals. Sync is provided on all three channels. A 9 pin female D-Sub connector is used for the output video connection.

All units may be switched to monochrome mode via an internal switch.

The CBG462 is available as packaged or as board level product. Board level products do not include the power supply and a 5VDC to 20VDC regulated power source must be provided. The standard board level product with a -01 suffix includes the standard video connectors that the cased product uses. For OEM applications, we can provide units with header and other connection types. Custom designed or modified versions are also available. MicroImage Video Systems has designed many custom derivatives of the standard color bar generator to meet the special needs of different applications. We would be glad to help with your application. We have also provided product at the chip level as well. Quantity discounts are available.

The CBG362 has a one year parts and labor limited warranty. All units are RoHS compatible.
