On January 23, Agilent Technologies, a Japanese subsidiary of major measurement equipment company Agilent Technologies, announced two types of physical layer compliance test software for equipment that uses the latest High-Definition Multimedia Interface (HDMI) 2.0.
The first is transmission test software that runs on the company’s oscilloscope “Infiniium,” which supports HDMI 2.0 transmission tests. The other is reception test software used with the company’s TMDS signal generation platform or the arbitrary waveform generator “M8190A”, which supports HDMI 2.0 reception tests.
HDMI technology is used in TVs, computers, video / image equipment, etc., and interoperability is emphasized. Announced in September 2013, the HDMI 2.0 specification has significantly expanded bandwidth up to 18 Gbps, featuring new features, improved resolution, and support for up to 32 audio channels. This HDMI 2.0 transmission test solution is being extended based on the HDMI 1.4b transmission compliance test software currently used by HDMI certification test centers around the world. It implements the most advanced functions required for HDMI 2.0 transmission tests, such as the transmission line load emulation function of the HDMI 2.0 standard cable model and the fixture embedding function that removes the transmission load of the test fixture. It also provides a reference equalizer emulation function that allows the characterization of the system under design using any model.
In the HDMI 2.0 transmission compliance test, the number of mouse clicks has been reduced and the operability has been improved. It also improves productivity with two new features. One is the user setting save / load function. The other is the test plan control function. This feature is a guidance feature for a device that covers all the required tests, a feature not implemented in traditional HDMI test solutions. It also supports automatic control of the microwave switch matrix, making it possible to control all high-speed signals on software without the hassle of reconnecting.
The HDMI 2.0 reception compliance test solution is offered as an extension of the TMDS signal generator “E4887A” or as a new addition to the arbitrary waveform generator “M8190A”. The new cable emulator will also allow existing “E4887A” users to upgrade to the HDMI 2.0 reception test solution. In addition, a low-cost, compact arbitrary waveform generator “M8190A” has become available. With the “M8190A,” waveforms can be digitally synthesized and the desired distortion can be generated internally with a single unit, eliminating the need for an external cable emulator. This function eliminates the need to control external devices and reconnect cables, increasing reliability. Test solutions based on arbitrary waveform generators provide accurate measurement results, are more flexible than other HDMI test solutions, and reduce development costs.
In addition, BitifEye offers a product that complements this HDMI 2.0 reception compliance test solution. BitifEye offers HDMI 2.0-enabled upgrade solutions, including HDMI frame generation software, phase adjusters, and an HDMI status / control data channel control kit with new scramble support.
The price is about 920,000 yen (excluding tax) for the HDMI 2.0 transmission compliance test software and about 1.39 million yen (excluding tax) for the HDMI 2.0 reception compliance test software. It has already started selling and shipping.
