HDMI 2.1 FRL Compliance Test Solution Datasheet说明书

HDMI 2.1 FRLCompliance Test Solution DatasheetEngineers 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.Key featuresConformance to HDMI 2.1 Standards and Compliance TestSpecification 2.1 (CTS)Simple and easy setup to perform measurementsThe TekExpress based software solution allows to completelyautomate the execution of all source and sink measurements.There is no “external plumbing” such as delay lines, amplifiers or biasteesProgrammatically change amplitude, bias voltage, and skew with AWG-HD. No need to change the connection or manual intervention betweenthe tests.Superior performance across industry. Completes all sinkmeasurements for one data rate in less than 20 minutes.Fully integrated with EDID/SCDC emulatorsStatistically based Pass/Fail results, quick results with Pass/Failnotification, and limit margins. Detailed reports including BER error oneach lane.Provides link training debug capabilityCompletely automated pattern calibration software Multilane calibration supportFully automated HDMI 2.1 FRL compliance testingThe sink testing requires a source, capable of generating a wide range of test patterns and the ability to add precise amount of impairment to the output signal. The jitter, tolerance, skew, sensitivity and timing testing with repeatability are critical. For customers who want to reduce test times with the performance to meet the new standard requirements, Tektronix offers a complete test solution for HDMI 2.1 sink testing.
