AWG supports HDMI 2.0 receiver compliance testing

 

In addition to the N5990A software’s HDMI sink test option 151, the automated test solution includes option 350 for HDMI extended display identification data (EDID), consumer electronics control (CEC) and high-bandwidth digital content protection (HDCP) tests.

All relevant HDMI 1.4 and 2.0 tests are supported, including source and sink transition minimised differential signalling (TMDS) protocol 6G and scrambling tests.

With the industry’s first channel duplication capability, the M8195A-based signal generator allows for the addition of an intra-pair skew within the instrument.

This eliminates the need for external delay lines, which in the past, engineers had to adjust manually during a sensitive calibration process.

This approach also allows for a very quick check on the design margin of a customer’s device under test (DUT) as engineers can dynamically adjust the intra pair skew in real time.

Furthermore, the output stage of the M8195A signal generator was designed to natively support the signalling levels required for HDMI compliance testing, which removes the requirement for external Bias T components in the signal path.

The signal generator only requires an HDMI 2.0 approved test fixture in order to connect to an HDMI sink DUT.

No reconnection of external accessories is required when the HDMI TMDS receiver electrical compliance tests are performed.

The new TMDS signal generator system consists of two M8195A 2-channel modules and a M8197A multi-channel synchronisation module.
