This product has been retired.

The Extron VTG 300 is a handheld, battery-operated video and audio test generator featuring high resolution computer-video, HDTV, and 16:9 rates, as well as standard definition NTSC or PAL video rates for RGB, component video, S-video, and composite video. The VTG 300 is lightweight and compact for portable field use or bench testing. As a versatile, broadcast quality reference tool, this test generator can be used for projector set-up, performance evaluation, alignment, convergence, calibration, synchronization, troubleshooting, and accurate video and audio signal reproduction in professional AV applications.

The VTG 300 features a streamlined user interface with an easy-to-read, backlit LCD display and rubber pushbuttons for direct and simple access to video and audio functions. The 13 video test patterns can be used with any of the 34 video scan rates. An integrated audio tone generator includes six audio test signals on a balanced, phantom power immune XLR connector, as well as unbalanced on a female RCA connector and 3.5 mm dual-channel mono mini jack. When the test generator is turned off, the most recent settings are stored and automatically recalled when the unit is turned on again. The VTG 300 is housed in a compact, rugged enclosure. It comes with a protective rubber boot to guard against severe environments and prolong the lifespan of the test generator. The boot is also reversible to cover and protect the front of the unit when not in use.

Features

Video outputs: RGB/component video on a 15-pin HD connector, S-video on a 4-pin mini DIN connector, and composite video on a BNC connector

Audio outputs: 3-pin XLR connector, RCA connector, and 3.5 mm mini stereo audio jack

Handheld and battery-powered

13 video test patterns — Included are 32 x 24 and 32 x 18 crosshatch patterns, H pattern, SMPTE color bars, EBU color bars, 8-color split bars, 32-level split grayscale, ramp, alternating pixels, multiburst, 20% window, 80% window, and flat field - all the essential patterns for accurately testing and calibrating a display.

Six audio test signals — Test signals include sine waves, square waves, pink noise, white noise, polarity, and frequency sweep. Basic audio testing is helpful for loudspeaker calibration, frequency settings, distortion, and polarity verification in audio cabling.

34 selectable output rates, including high resolution computer-video, HDTV, and NTSC/PAL video — Provides scan rates to support high resolution computer-video, HDTV, 16:9, plasma, RGB, as well as standard definition component video, S-video, and composite video.

Broadcast quality video encoder on composite and S-video outputs — Ensures compliance with SMPTE and NTSC/PAL standards for accurate video performance.

Screen Saver mode — An adjustable timer can be set to engage the VTG 300 and VTG 300R in Screen Saver mode, with either the video output muted or as a repeating sequence of test patterns.

Small, rugged enclosure with protective rubber boot

Highly reliable, energy-efficient external universal power supply included, replacement part #70-778-01 — Provides worldwide power compatibility, with high demonstrated reliability and low power consumption for reduced operating costs.
