Video Signal Generator with Three Vertical Bar Pattern – IEC 62368 Compliant Display Testing Tool

Video Signal Generator with Three Vertical Bar – IEC 62368 RDL-100 Display Test Tool

The Video Signal Generator with Three Vertical Bar (RDL-100) is a high-precision test instrument manufactured by KingPo, specially designed to output standard three vertical bar (RGB) patterns and a full range of video formats for display performance validation and safety testing in AV/IT equipment. Compliant with IEC 62368-1, this generator delivers stable, repeatable signals through CVBS, YPbPr and HDMI interfaces, enabling fast verification of color accuracy, brightness uniformity, resolution support and electrical safety.

Key highlights:

• Classic Three Vertical Bar Pattern — Industry-standard RGB bars for quick color reproduction and screen uniformity checks
• Broad Format Support — Covers PAL/NTSC SD, HD (720p/1080i/1080p), and 4K ultra-HD (3840×2160p 25/30Hz)
• Multiple Interfaces — HDMI, YPbPr, CVBS for seamless connection to TVs, monitors, projectors and more
• High Stability & Repeatability — Precision signal generation ensures consistent, reliable test results

In TVs, monitors, projectors, laptops and tablets, accurate color, contrast and resolution are essential for user experience and safety compliance. The KINGPO generator simulates real video input conditions, helping manufacturers, certification labs and QA teams detect defects (color shift, mura, dead pixels) early, reduce rework and accelerate market entry.

This equipment combines robust construction, intuitive front-panel controls and multiple output options, providing certification-grade performance for CE, UL, CB Scheme, CCC and EMC testing.

Core Role & Purpose

The Video Signal Generator outputs three vertical bar patterns and test signals to:

• Verify color accuracy and reproduction using standard RGB bars
• Check brightness, contrast and screen uniformity
• Confirm resolution and format compatibility (SD to 4K)
• Ensure compliance with IEC 62368-1 video signal requirements
• Support safety and electromagnetic compatibility (EMC) experiments

It provides controlled, stable signals to simulate real-world video sources, helping ensure display quality and electrical safety.

Professional Construction & Technical Precision

These features guarantee accurate, repeatable testing across a wide range of display devices.

System Display & Controls

• System Display Displays the system control software interface with touch screen functionality. Users can easily:
  • Select system signals
  • Choose video formats
  • Configure digital TV modulation signal parameters
• Keypad Composed of navigation keys (up, down, left, right, etc.), a numeric keypad, and function keys, enabling convenient and intuitive software operation and control.
• USB Interface Convenient USB port for connecting external devices such as a mouse, keyboard, USB flash drive, and other peripherals.
• Power Key Controls the system power on/off and switching.

Interface Descriptions

• Y / CVBS, Pb, and Pr Interfaces These are the output interfaces for analog TV composite video signals and component video signals.
  • When the signal format is PAL or NTSC, the Y / CVBS interface outputs a composite video signal (CVBS).
  • In other formats, it outputs the luminance signal (Y) of the component video signal.
• L and R Audio Interfaces Audio output interfaces.
  • L represents the left channel (Left).
  • R represents the right channel (Right).
• HDMI Interface Digital video signal output interface.
• System Peripherals Interface Convenient interface for connecting external devices such as monitors, mice, keyboards, USB drives, etc.
• System Power Supply Interface and Switch Used to connect and control the system power supply.
