MHL 3.0 advanced analysis and compliance test for portable products
The MHL 3.0/CTS 3.2 standard supports 4K (UHD), HD video and 7.1 surround-sound audio while simultaneously charging the connected device. There are now more than 400 million MHL products in use by consumers, developed by the growing base of more than 200 global adopter companies. MHL-enabled products include adapters, automotive accessories, AV receivers, Blu-ray Disc players, cables, DTVs, media sticks, monitors, projectors, smartphones, tablets, TV accessories, and more. Tektronix has offered a comprehensive set of automated PHY and protocol layer test solutions since the first MHL specification was released in 2010.
"As an important mobile industry standard, MHL is evolving rapidly with new features and new test strategies for transmitter input and receiver output test points," said Brian Reich, general manager Performance Oscilloscopes, Tektronix. "We are continuing to offer customers developing MHL products important advantages such as simpler test setup for faster test cycles and more comprehensive test coverage including industry proven direct synthesis based receiver test solutions and backward compatibility testing."
Opt. MHD3 software for use with Tektronix DPO/MSO70000 oscilloscopes supports the full range of MHL transmitter and receiver electrical tests. It provides backward compatibility testing with MHL 2.1 and 1.X (available in Opt. MHD) and supports MHL 3.0/CTS 3.2 source/sink and dongle devices.
The full solution provides faster execution for the full range of tests outlined in CTS 3.2 through the use of optimised algorithms. TMDS and eCBUS eye-diagram support has auto-mask fit for debugging and automatic mask adjustment. The solution also enables engineers to perform BER test with calibrated patterns for Transmitter Input test. The Auto calibration module generates the required calibrated patterns based on the Jitter from DUT signals.
Setup is simplified through the use of connection diagram screenshot pop-ups during execution that help reduce setup mistakes. The solution also offers complete programmatic interface support for integrating the MHL 3.0/CTS 3.2 test solution into users’ test environments. Elaborate reporting options with user-selectable fields and formats for report customisation are also available.
The completely automated Opt MHD3 solution for MHL3.0/CTS3.2 is available now; pricing starts at $10,000
