VTG 400D Extron Programmable Video and Audio Test Generator

The Extron VTG 400 / VTG 400D Programmable Video and Audio Test Generators are advanced, programmable, and upgradeable video and audio test generators that deliver accurate, wide bandwidth video signals and high performance audio test signals. These test generators are professional quality reference tools for set-up, performance evaluation, calibration, and troubleshooting audio and video systems.

The VTG 400 offers a comprehensive array of video test patterns, as well as a suite of audio reference signals. Video is output simultaneously as RGB, component video, S-video, and composite video, while stereo audio output is both balanced and unbalanced. An SDI and HDSDI output is included with the VTG 400D.

The VTG 400 is designed to provide a wide variety of reference signal types. A total of 96 output scan rates are available for high resolution computer-video, as well as HDTV, NTSC, and PAL. Up to 180 additional rates can be programmed into the VTG 400. The audio test generator is fully compatible with professional and consumer audio equipment, and delivers accuracy at microphone level.

Operation of the VTG 400 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 VTG 400 can be programmed and upgraded using RS-232 and Extron control software, including new test patterns and custom scan rates.

A powerful and innovative feature is Scope-Trigger output, which enables analysis of a selected area within the video image using an oscilloscope. Scope-Trigger greatly simplifies and speeds up oscilloscope set-up for video signals by using a specially generated trigger signal, precisely timed to a user-defined target location on the image.

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