Keysight Technologies Introduces First MHL 3 Source Compliance Test Software

01/07/2015

Keysight Technologies, Inc. (NYSE: KEYS) introduced compliance test software for the latest Mobile High-Definition Link (MHL) specification. The MHL 3 source compliance test software allows engineers to test their MHL 3 transmitters the same way they are tested at official authorized MHL compliance test centers using Keysight Infiniium oscilloscopes.

Leading manufacturers are implementing MHL technology in consumer products such as tablets, mobile phones and automotive audiovisual accessories, which requires them to pay close attention to device interoperability. The MHL 3 specification, published in August 2013, offers a significant increase in bandwidth (up to 6 Gbps) to support higher resolution and a new bidirectional high-speed communication path between the portable device and a display.

Keysight's N6460B transmitter compliance solution builds on its MHL 2 transmitter compliance test software that is also currently used worldwide in MHL authorized test centers. The new software offers test capabilities now required for MHL 3 transmitters, such as a dedicated TMDS lane and new functionality in the CBus, referred to now as eCBus, that includes forward and reverse transmission validation.

"Consumers want to be confident that the MHL products they purchase will deliver the performance and interoperability they desire, ensuring that devices work together effortlessly," said Solomon Langley, general manager, Simplay Labs. "Keysight's development engineers have worked on the N6460B compliance software with our validation teams on measurement algorithms to optimize accuracy and usability. Keysight is an important piece of our interoperability program, and we look forward to continuing to work with them as we move to future versions of the MHL specification."

The Keysight MHL 3 compliance software includes new features along with test suites for all previous versions of MHL, which are required to validate interoperability of MHL 3 devices. The software feature set includes:

  • MHL 1, MHL 2 and MHL 3 test suites
  • Cable model and equalizer setup for complete control in what-if analysis as well as standard compliance testing
  • User-defined mask setup to suit individual company goals as well as standard masks required in compliance testing
  • DUT automation control for MHL 3 unattended testing using Simplay Labs test accessories
  • Saved waveform analysis to import waveforms for remote support or offline analysis
  • User comments for in-depth details in test reports
  • Calibration test suites for MHL TMDS receiver test as well as source device eCBus receiver testing

Keysight's MHL source compliance testing solution includes:

Full MHL 3 link analysis requires Keysight's receiver cable compliance testing solutions, including Keysight E4887A TMDS signal generators, the M8190A arbitrary waveform generator and N5990A factory automation software. The receiver compliance solution is complemented by products from Keysight's solutions partner BitifEye. BitifEye products include test fixture and an MHL upgrade of BitifEye's frame generator software.
