HDMI Compliance Test Software

TekExpress HDMI Source Compliance Test Application for HDMI 2.1, HDMI 2.0, HDMI 1.4

線上參閱:

HDMI 2.1: Engineers designing and validating the HDMI physical layer of their devices face constant pressure to improve efficiency. Designers need to perform a wide range of compliance tests quickly and reliably, right on their bench. The HDMI 2.1 is known for Fixed Rate Link (FRL) supports up to 4 k at 120 Hz or 8 k at 60 Hz for both compressed and uncompressed video content. The FRL supports only predefined discrete data rates - 3 Gbps, 6 Gbps, 8 Gbps, 10 Gbps, and 12 Gbps on each of its 4 lanes, which means the FRL supports a post encoded link bandwidth of up to 48 Gbps.

HDMI 2.0: HDMI 2.0 supports features like 2160p (also known as Ultra HD/4K 2K 60/50 Hz), operating at 5.94 Gbps.

Option HDM compliance software automates a comprehensive range of tests according to CTS 2.0.

Eye diagram analysis

HDMI 2.1 Eye diagram capability: Displays the eye diagram of the High-Speed signal with option DJA enabled on the oscilloscope for test HFR1-7 Data lane Eye Diagram. This test evaluates the waveform parameters over a significant interval of time to verify that with proper clock recovery and equalization, there is no signal incursion into regions defined by a mask to result in correct demodulation of data. The equalization (CTLE and DFE is applied for data rate equal to 12 Gbps; while CTLE only is applied, for any other data rate) on the resulting summed waveform for a wider eye-opening.
