Extron Electronics announced that the VTG 400DVI is now available. The VTG 400DVI is a pro-grade video and audio test generator for setting up, testing, calibrating, and troubleshooting complex video and audio systems.

The test generator offers DVI output for use with digital display devices, and delivers accurate, full-bandwidth video signal reproduction and high performance audio test signals, according to the company. Analog high-resolution computer video, Component video, S-video, and Composite video are also supported. When used with DVI devices, the VTG 400DVI will display the native resolution whenever new EDID data is received, says the company. The VTG 400DVI also offers Scope-Trigger, a feature that enables analysis of a specific area within the pattern image using an oscilloscope.

"The VTG 400DVI is a professional-quality reference tool with powerful capabilities that enable proof of performance for commissioning and testing AV systems," said Lee Dodson, vice president of marketing for Extron Electronics, in a statement. "By including the DVI output signal on the VTG 400DVI, we can now support devices and systems that use this popular digital video format."

The VTG 400DVI offers 34 video test patterns--several with adjustable levels--and seven audio test reference signals with selectable frequencies and output levels. A total of 113 output scan rates are preprogrammed, including high-resolution computer video, HDTV, NTSC, and PAL. A control panel offers access to video or audio test signals and settings. The VTG 400DVI can be programmed and upgraded with custom scan rates through the RS-232 port using the included Extron control software.
