Model Details

700 TV lines at 35Fl Luminance for 100% ofwindow signal, scans 50Hz-10MHz RGB & up to 7MHz Monochrome, Convergence area .3mm, Pitch .43 mm, RGB/NTSC/Y,R-Y,B-Y, Underscan 90% of Normal



High Performance Cathode Ray Tube


!In-line Self Converging Electron Gun assures convergence stability.

!Controlled Phosphors to ABS or EBU Standards provide consistent and

known colorimetry.

!Black Matrix surrounding Phosphor Dots assures high contrast under

bright ambient lighting.

!13V and 19V units available.

Digital Control System (DCS)

The preset control system is completely digitized with the 8 bit MPU and

the 10 bit D/A converter. It enables several status indications, and auto

setup capability with an optional PROBE (ASP-15C). Since a rotary

encoder for preset controls and variable resistors for manual controls

(CONTRAST,, BRIGHTNESS, CHROMA, HUE) are provided, the 20-

series monitors can be adjusted in the same manner as conventional

analog-controlled monitors.

Auto Setup System

By using an optional Auto Setup Prove (ASP-15C), the following

functions can be automatically setup at a reference level or stored in less

than 50 seconds.



Remote Control Operation

An infrared remote controller (RCT-20) is provided as an option. With

each of them, the following functions can be remotely controlled for up

to 99 monitors.














Beam Feedback System(BFS)

To insure long-term black level stability, the 20-series monitor incorporates

Beam Feedback System(BFS) which detects CRT cathode current deviation and

eliminates brightness changes due to changes in CRT emission.

Adaptive Comb Decoder*

By incorporating a CCD 1H delayline into the standard comb filter, cross

luminance and cross color are improved over conventional monitors. In

addition, by replacing it with an optional Adaptive Comb Filter Decoder*

(NTSC only), performances of 20-Series are significantly improved for

precision color monitoring or graphics display.

Improvements include:

!Chroma edges are greatly improved by patented process based on use of

luminance transitions.

!Dot crawl at chroma transitions is eliminated.

Wide Range of Input Capabilities

The 20-Series can accept 3 composite video inputs and an RGB or a component

(Y, R-Y, B-Y) input as standard. Optional plug-in decoder boards are available

for Digital (D1, D2, D3), PAL-B, SECAM, PAL-M TV standard systems.

Modular Concept

The 20-Series provides modular construction for ease of repair and adjustment.

The boards of video system are plug-in, and many of the boards can be removed

with the monitor mounted in a rack.
