Introduction This section provides an overview of the VTG 300 and VTG 300R and describes their features. About the VTG 300/300R The Extron VTG 300 and the VTG 300R are portable, hand-held video and audio test generators. The VTG 300R features an integrated battery pack and charger, otherwise both models offer the same functions and features. “VTG” and “video test generator” refer to both the VTG 300 and the VTG 300R and are used interchangeably.
Operation This section describes: • Front Panel Features • Left Side Panel LED (VTG 300R model only) • Right Side Panel Power Input • Top Panel Video Output • Bottom Panel Audio Output • Example Applications • Connecting Audio Outputs • Menus, Configuration, and Adjustments • Additional Functions • Audio Testing Features • Video Testing Features • Installing the VTG 300 Batteries • Conserving the VTG 300 Battery Life • Recharging the VTG 300R • Installing the Protective Boot Fr
The audio output level settings for all audio signal types are retained after the VTG is powered off. The default setting is -28 dBu for polarity and -10 dBu for all other signal types. NOTE: • If the Level buttons are held down for more than one second, the VTG will automatically increment the level adjustment in the direction indicated by the button.
Left Side Panel LED (VTG 300R model only) Battery charge status LED — The amber LED lights steadily when the VTG is being charged, and blinks steadily when the VTG is fully charged.

Audio Testing Features The VTG can output from among six different audio signal formats. The audio level can also be selected from a range of levels available for each audio format. Depending on the audio signal format, the audio frequency may be selected from a range of values (see Front Panel Features on page 2 for button descriptions). Selecting Audio Signals The following table summarizes the six audio signal formats available through the VTG.
Setting the Audio Frequency The audio frequency for each audio signal type is selected from a range of values using the or Frequency buttons and observing the LCD. The following table lists the available frequencies. Audio Signal Format Audio Frequencies Pink Noise Not Applicable White Noise Not Applicable Sine Wave 20 Hz, 25 Hz, 31.5 Hz, 40 Hz, 50 Hz, 63 Hz, 80 Hz, 100 Hz, 125 Hz, 160 Hz, 200 Hz, 250 Hz, 315 Hz, 400 Hz, 500 Hz, 630 Hz, 800 Hz, 1.0 kHz, 1.25 kHz, 1.6 kHz, 2.0 kHz, 2.5 kHz, 3.
