Testing Mobile High-Definition Link compliance

Tektronix Inc.is providing a Mobile High-Definition Link (MHL) compliance test solution that works with its DPO/DSA/MSO70000 series oscilloscopes to enable seamless testing and analysis from the MHL PHY layer to the link layer and back.

Created by the MHL Consortium , the MHL specification is an HD video and digital audio interface for connecting mobile phones and portable devices to HDTVs and other home entertainment products. The Tektronix MHL test solution is based on the MHL Compliance Test Specification (CTS) 1.1 released in June, 2011.

The MHD option automates a range of MHL compliance tests and the MHL Protocol Analyzer software leverages the same Tektronix real-time scope used for physical layer testing to provide a unique MHL protocol solution, which enables seamless transition between physical and link layer.

For MHL receiver and adapter tests, Tektronix provides a setup with all impairments added to the MHL signals using direct synthesis-based capabilities of the Tektronix AWG7000 series arbitrary waveform generators. This simplifies the setup and testing across the range of tests performed. Tektronix also offers an MHL cable test solution based on time domain reflectrometry tests used with the DSA8300 series sampling oscilloscope.
