We can collect 45 acquisitions and 90 waveforms in about one hour, greatly accelerating analysis and reporting.

Detailed Reporting

Our system automatically captures waveforms, analyzes results, and generates comprehensive test reports. This end-to-end approach streamlines the entire HDMI testing process, giving you actionable insights to optimize product design and compliance.

Challenges that HDMI testing facing

The ever-evolving digital landscape—encompassing high-definition content, 8K video, and immersive audio—together with about 14 billion HDMI-enabled devices worldwide, introduces numerous challenges for HDMI testing. Keeping pace with diverse HDMI specifications and ever-higher performance demands requires thorough HDMI cable and audio and video quality testing:

Ever-Increasing Resolutions

Moving from 1080P to 4K, 8K, and beyond imposes stricter requirements on cable bandwidth and signal integrity. Manufacturers and test labs must validate that signals remain stable under higher data rates.

Elevated Audio Demands

As HDMI versions advance, so do audio specifications. Features like Dolby TrueHD, DTS-HD, ARC, and eARC require meticulous HDCP testing and EDID testing for HDMI systems to ensure proper format support and seamless interoperability.

Reliability and Stability

Consumers expect HDMI cables and devices to operate consistently without signal dropouts or interference. Thorough HDMI cord testing and environmental testing help identify issues such as signal attenuation or noise, ensuring dependable performance in real-world conditions.
