About this Guide
This guide describes the functionality of the DVI 110 and provides procedures for
connecting and operating it.
In the guide, the terms “regenerator” and "DVI 110" are used interchangeably to refer to
the product.
About the DVI 110 Signal Regenerator
The Extron DVI 110 is a compact, 1 inch (2.5 cm) high, one-eighth rack wide DVI signal
regenerator that maximizes the quality of a digital signal at the beginning of its path by
regenerating the signal. The DVI 110 reshapes a poor quality output signal, providing
optimal image quality for HDTV signals.
Signal Eye Pattern
The following illustrations show the "eye pattern" of DVI output from a test generator
before and after regeneration via a DVI 110. An eye pattern is a representation of a digital
signal on an oscilloscope in which a digital data signal is repetitively sampled. Distortion
in the signal waveform due to interference and noise appears as a "closing" of the eye
pattern, as shown in the "Before Regeneration" illustration, below on the left.
After the signal passes through the DVI 110 and is regenerated (shown in the "After
Regeneration" illustration, below on the right), the "eye" appears more open, indicating a
clear, undistorted signal.
