The Extron VTG 300 and VTG 300R are handheld, battery-operated
video and audio test generators featuring high resolution computervideo, 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
3.5 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 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.
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
is connected, the battery can be recharged while the VTG 300R is
in operation. Fully charged in 8 hours, the VTG 300R can provide
up to 5 hours of continuous operation.
