Atec 2225 User 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,

question and answer query to guide
the user in setting up all timing and
pattern parameters. Preformatted and
fully programmable ICON patterns,
such as Circle, Line, Cross Hatch,
Rectangle, Dot, Marker, Character,
String, ColorBar, Gray Scale, make it
very easy for the user to create any
test patterns. Also, real-time error
message is displayed to help identify

pattern, and control functions can be set by the
instrument front panel keypad, or from the remote
controller via RS232C interface.

Over Range Pixel Rate Simulation

The instrument automatically scales down the pixel
rate and maintain the same H/V frequencies when an
over range pixel rate is entered.This unique function
allows the instrument to operate with any display monitor
up to 480MHz pixel frequency.

Flexible Output Control

Programmable test loop allows the user to switch
timing/pattern combination output to the monitor in an
automatic sequencing mode or in a manual control mode
using one key operation.

Also, the user has instant on/off control of individual
R, G, B or Reverse pattern using front panel one key
operation.

Additionally, the instrument has 16-bit user
programmable TTL output ports to control any external
device.

Comprehensive Pattern & Timing Library

Standard test patterns such as SMPTE, High-Voltage
Regulation, X-Hatch, Color Delay, 256-color pattern,
Interlace Check, Dynamic Motion Pattern, etc., are built­in a pattern library. These patterns are easily called and
displayed on the monitor screen for test or demo
purpose.

Over 50 commonly recognized timing formats,
including MDA, PGA, VGA, VGA-8514, etc., are factory
installed in the instrument memory. The user can
instantly recall any of the standard timing formats most
suitable for his monitor test application.
