The Extron VTG 400DVI is an advanced, programmable, and upgradeable Video and Audio Test Generator that delivers accurate, full bandwidth video signal reproduction and high performance audio test signals. This test generator is a professional quality reference tool for set-up, performance evaluation, calibration, and troubleshooting audio and video systems.

The VTG 400DVI offers a comprehensive array of video test patterns, as well as a suite of audio reference signals. High resolution RGB computer video is output simultaneously on BNC and 15-pin HD connectors. NTSC and PAL video is output simultaneously as RGB, component video, S-video, and composite video, while audio output is both balanced on XLR and unbalanced on a 3.5 mm mini jack. A DVI-D output is included on a female DVI-I connector. Additionally, the LCD of the VTG 400DVI is capable of displaying the native resolution of a DVI device when new EDID data is received.

The VTG 400DVI is designed for universal video display compatibility. A total of 113 output scan rates are pre-programmed which include high resolution computer video, HDTV, NTSC, and PAL. Up to 180 additional rates can be programmed into the VTG 400DVI. The audio test generator is fully compatible with professional and consumer audio equipment, and delivers accurate performance for microphone level inputs while being phantom power resistant.

Operation of the VTG 400DVI is intuitive and convenient, with an easy-to-read LCD screen on the main panel, direct access buttons, and memory presets for quick saving and recall of user settings. The test generator can be programmed and upgraded with custom scan rates through the RS-232 port using the included Extron control software.

A powerful and innovative feature is the Patented Scope-Trigger™ output, which enables analysis of a selected area within the video image using an oscilloscope. Scope-Trigger delivers quick and easy oscilloscope operation with minimal effort. Any desired location, or pixel, within a video image can be accurately targeted and then simultaneously examined on an oscilloscope via a precisely timed trigger signal from the VTG 400DVI.

Housed in a rugged, lightweight metal enclosure, the VTG 400DVI is ideal for both field and permanent AV applications.
