Extron electronic VTG 300R Description, Features, Application Diagrams, Panel Drawings

DESCRIPTION

The Extron VTG 300 and VTG 300R are handheld, battery-operated video and audio test generators featuring high resolution computer- video, plasma, 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 300R features a rechargeable battery with an internal charger, while the VTG 300 operates on four AA batteries. Both models can be powered when the included external power supply is connected. When fully charged, the VTG 300R can operate continuously for up to approximately 5 hours. Each product is lightweight and compact for portable field use or bench testing. As versatile, broadcast quality reference tools, these test generators can be used for projector set-up, performance evaluation, alignment, convergence, calibration, synchronization, troubleshooting, and accurate video and audio signal quality reproduction in professional A/V applications.

The VTG 300 and VTG 300R feature streamlined user interfaces with easy-to-read, backlit LCD displays 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 XLR connector, as well as unbalanced on a female RCA connector and

3.5mm 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 and VTG 300R are housed in compact, rugged enclosures. Each comes with a protective rubber boot to guard against severe environments and prolong the lifespan of the test generator.

FEATURES

■ 34 scan rates – 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 – Ensures compliance with

SMPTE and NTSC/PAL standards for accurate video performance.

■ 13 video test patterns – Included are crosshatch (32x24, 32x18),

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.

■ Video output connectors – A 15-pin HD female connector is

provided for RGB and component video output signals, while

BNC female and 4-pin mini DIN female connectors are provided

for composite video and S-video signals, respectively.

■ Six audio test signals – Test signals for the VTG 300 and

VTG 300R 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.

■ Portability – Small, rugged, handheld enclosures, along with the

included protective rubber boots, make the VTG 300 and

VTG 300R excellent tools for technicians in the field.

■ Power options – The VTG 300R can be powered using the

integrated rechargeable battery, while the VTG 300 operates on

four AA batteries (not included). Both models can also be

powered using the included external international power supply

(part # 70-055-03).

■ Integrated charger (VTG 300R only) – When the power supply
