This crosshatch pattern can be used to set projector focus and geometry. For CRT projectors,
this pattern is for examining and adjusting both static and dynamic convergence, so that the
red, green, and blue video signals are aligned throughout the image.

This pattern is used to check or evaluate video clamping stability, focus for projectors, and
video pulse response, as well as to simulate text. The user can toggle between white-on-black
and black-on-white.

SMPTE Color Bars (with PLUGE pattern)
For NTSC video equipment, the SMPTE color bars are used to set up tint and color, while the
PLUGE video pattern is for adjusting brightness and contrast.
EBU Color Bars
The EBU color bars are primarily used to set up color for PAL video equipment.
Color Bars (8-color split)
This pattern is used for testing all of the video color channels and setting video drive levels. It
is also used to check low frequency crosstalk between the red, green, and blue color channels.

32-level Split Grayscale
With two opposing rows of 32 stepped bars of gray between the lowest and highest levels,
this pattern is used for setting and assessing grayscale tracking, and evaluating contrast
linearity on displays.
Ramp
This is used to evaluate the performance of a display or video processor on the basis of its pixel
bit depth capability. The pattern should appear to be smooth, with no contouring or
stepping.

80% Window
A window at 80% (80 IRE) video level, surrounded by black, is used in fine tuning the
color balance (or grayscale) of a display with the aid of a color analyzer. The gain (or
drive) setting is fine tuned for each of the red, green, and/or blue color adjustments.
20% Window
A window at 20% (20 IRE) video level, surrounded by black, is used in fine tuning the color
balance (or grayscale) of a display with the aid of a color analyzer. The bias (or offset) setting
is fine tuned for each of the red, green, and/or blue color adjustments.
VTG 300 AUDIO SIGNAL FORMATS
Pink Noise
White Noise
Sine Wave
Random noise that has constant energy per octave. Used in loudspeaker testing and calibration.
Random noise that has an equal energy distribution across all frequencies between 20 Hz and 20 kHz.
Used in detecting distortion. The frequency can be set from 20 Hz to 20 kHz (in 1/3 octave steps).
Square wave signal with 50% duty cycle and no DC offset. The frequency can be set from 20 Hz to 5 kHz.
Square Wave
Swept Sine Wave Varies the frequency of a sine wave signal continuously from 20 Hz to 20 kHz. Used to detect driver defects and mechanical sources of distortion.
Polarity test
Proprietary waveform used in verifying the polarity of audio cabling.
