Atec Chroma-2225 - Manual

the instrument has built-in user programmable
NVRAM device and optional memory card to let
the user store his customized timings, patterns,
icons for instant recall.
In test application , the user can program and
display various timing/pattern combinations on
the monitor in an automatic sequencing mode
or in a manual control mode. The screen
drawing, including blinking function and motion
picture, makes you operate more easily and
friendly. It also has the power-saving mode test
capability for testing your monitor's compliance
with the standard of display power
management. The instrument can be operated
using the front panel keypad or from the remote
controller via RS232C.
All the features and benefits applied to the
Chroma 2225 series allow you to fully
characterize the monitor's high-frequency
performance and high-quality image. In view of
the modern extremely demanding CRT monitor
industry where every pixel of monitor is critical,
the Chroma 2225 series must be your key to
success.
PROGRAMMABLE VIDEO
PATTERN GENERATORS
The Chroma 2225 series are fully
programmable, microprocessor-based
instrument for testing high resolution CRT
display monitors, projectors, and video printers.
Designed with precision phase lock loop (PLL)
frequency synthesizer circuit (25PPM
accuracy) , it is capable of generating
sophisticated video graphic display with 256
colors selection on every pixel. All horizontal
and vertical timing parameters are fully
programmable in one-pixel resolution.
Manufacturers of monitors, projectors, and
video printers can use the video pattern
generators for design characterization,
engineering, incoming inspection, production
testing, and product demonstration.
The instrument has built-in software to let the
user recall and edit test application of different
video frequencies, video levels, timing
parameters, patterns, and colors. It offers
factory-installed selections of universal timing,
pattern, and icon formats. Monitor testing, such
as display size, pincushion, linearity, focus,
geometry, resolution, contrast, color,
convergence, high voltage regulation, etc. can
be performed with minimum setup. Additionally,
