Introduction

About the VTG 300/300R

The Extron VTG 300/300R is a portable, hand-held video and audio test generator. The VTG 300R features an integrated battery pack and charger, otherwise both models offer the same functions and features. Both models are herein referred to as the “VTG” throughout this manual. Also, “VTG” and “video test generator” will be used interchangeably.

The VTG will generate video signals for computer, standard resolution video, HDTV, and 16:9 high resolution output rates. The composite video format conforms to the SMPTE 170M video standard. There are also six test pattern categories available for optimizing the display output: crosshatch, H pattern, color bars, grayscale, alternating pixels/multiburst, and white field.

For audio signals, the VTG offers basic audio test signals including sine and square waves, pink noise, white noise, polarity testing, and a frequency sweep from 20 Hz to 20 kHz.

Video output connectors include BNC, 4-pin mini DIN, and 15-pin HD connectors. Audio output is provided through RCA, 3-pin XLR, and 3.5 mm phone jack connectors.

The VTG 300 is powered by the included external power supply or four AA-type batteries (not included). The VTG 300R is powered by both the included external power supply and the built-in rechargeable batteries.

Installing the VTG 300 Batteries

Four AA batteries (rechargeable or alkaline) may power the VTG 300 and are easily installed. With the protective boot removed, use a flat blade screwdriver to loosen the captive screw and remove the rear battery pack cover. Replace the batteries while observing the correct polarity molded in the battery cradle as the batteries are installed. Reinstall the cover. See the illustration below.

Figure 2-14 — Battery installation

Conserving the VTG 300 Battery Life

In order to conserve battery life, batteries should be removed from the VTG 300 if it will not be used for an extended period of time. For information specific to the VTG 300R charging system, see the following section Recharging the VTG 300R.

Use these battery-saving features whenever possible to maximize the operational life of the VTG 300/300R batteries:

• Backlight mode (set to “Off”)

• Enable at power up (set to “Last Used”)

• Power off timer (set to as short an interval as possible)

Recharging the VTG 300R

Prior to using the VTG 300R for the first time, please be sure that the batteries are fully charged. The VTG 300R batteries are not covered under Extron’s three year warranty.

A fully discharged VTG 300R may take up to eight hours to reach the fully charged state. The charging process will automatically end after the batteries are fully charged or after eight hours have elapsed, whichever occurs first

Once fully charged, the VTG 300R may operate for up to five hours of normal use.

Although the VTG 300R may operate with the charger still actively powered and connected to the unit, the built-in batteries will have a longer life if the charger is used to fully charge the VTG 300R whenever the VTG 300R is powered off.

The amber charge status LED on the side of the VTG 300R will:

• blink steadily when the unit is fully charged.

• light steadily while the unit is being charged.

• not light if there is no input power to the charging circuit.

During the recharging process, a faint buzzing sound may be heard from the VTG 300R and/or the power supply. This is a normal occurrence and should be no cause for concern.

The VTG 300R charging circuit features short circuit protection. If a short occurs, a heat sensitive thermal fuse will cause an open circuit and prevent damage to the charging system.

When the batteries become fully charged or the charging time exceeds eight hours, the charging process will automatically end.

Installing the Protective Boot

The included protective rubber boot protects the VTG from abuse and shock while it is in use. The boot may also be reversed to protect the front panel when not in use, as shown below.
