One-Pixel Video Performance
The instrument offers video output with pixel rate up
to 250 MHz, horizontal scan up to 250 KHz, and vertical
scan rate up to 1KHz for high resolution monitor
application. All horizontal and vertical timing parameters
are fully programmable in one-pixel resolution.
Excellent Graphic Display
The user has instant access to generate the most
sophisticated color graphic display with 256 colors
selection on very pixel of a 4096
2048 display monitor.
Also, the user can use memory card to show natural
picture for checking total balance of color.
Easy to Set Up Timing & Pattern Formats
The instrument uses simple
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
invalid formats.
Versatile Operation
The instrument is very easy to operate by nature of
the powerful built-in software utility. All video timing,
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 built-
in 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.
