Arbitrary Waveform Generator supports HDMI 2.0 Receiver Compliance Testing
20 July 2016 – Keysight Technologies announced that the M8195A 65 GSa/s arbitrary waveform generator (AWG) supports an integrated HDMI 2.0 receiver compliance test solution. The N5990A automated compliance and device characterization test software offers the broadest HDMI 2.0 test coverage in the market and now allows fast and reliable HDMI 2.0 testing with the M8195A AWG.
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 minimized differential signaling (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 signaling 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 synchronization module.
“This signal generator configuration sets a new standard for simplifying HDMI receiver compliance test,” said Satish Dhanasekaran, general manager and vice president of Keysight’s Wireless Device & Operators organization. “This solution addresses the need for more efficient and consistent certification processes in compliance test labs and authorized test centers.”
“With a sample rate of 65 GSa/s and an analog bandwidth of 25 GHz, the M8195A based TMDS signal generator system is well suited to support future revisions of the HDMI standard,” Dhanasekaran added.
