HDMI interface testing

Your HDMI interface testing challenges

The primary goals of HDMI physical layer validation are to:

• Achieve compliance with HDMI standards
• Ensure interoperability between diverse devices
• Maintain robust signal integrity
• Verify performance across various resolutions and data rates.

This comes with a range of challenges, including:

• Time-consuming test setup: Manually setting up a compliance testing can be a lengthy process that is prone to error.
• Hardware and software requirements: Identifying the necessary hardware, software and accessories for effective testing can be complex and confusing.
• Source output configuration: Properly configuring the HDMI device-under-test (DUT) source output is critical for compliance testing but can be challenging to manage.
• Root cause analysis for compliance failures: When compliance tests fail, conducting a thorough root cause analysis to identify and resolve issues can be a daunting task.

High-performance solutions for HDMI interface pre-compliance testing

The Rohde & Schwarz solution for HDMI source physical layer pre-compliance testing covers HDMI 1.4b and HDMI 2.1. It is a pre-compliance test solution, meaning that it is not recognized by the HDMI Forum but follows the specification published by HDMI.

The solution:

• R&S®RTP oscilloscope has a customized frontend ASIC and real-time processing hardware that enables high-class signal integrity and a fast acquisition rate.
• ScopeSuite test automation software simplifies the complex challenges associated with testing for HDMI 2.1 (TMDS) and HDMI 1.4 for pre-compliance.
• Advanced software features, such as advanced eye and advanced jitter analysis, offer deeper insights into device performance.
