Tektronix Inc. releases an automated test solution for the Mobile High-Definition Link (MHL) Compliance Test Specification 2.0 which covers the transmitter (Tx), receiver (Rx) and dongle testing for PHY and protocol layers.

The one box solution for PHY and protocol testing is coupled with a direct synthesis based solution for Rx testing that reduces errors.

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. Tektronix announced a comprehensive test solution for MHL 1.2 earlier this year, and as a contributor to the standard, is moving quickly to support the latest specifications as they are released. MHL CTS 2.0 was released on October 16, 2012 and enables a number of important new innovations including PackedPixel Mode and 3D which will mandate additional testing.

Tektronix's innovative MHL protocol analyser software leverages the same Tektronix real-time oscilloscope, such as a DPO/DSA/MSO70000 Series, used for physical layer testing to provide a complete MHL protocol test solution. This one box solution enables a seamless transition between physical and link layers.

Testing efficiency is further enhanced with direct synthesis-based Rx and dongle testing that provides accurate MHL signal generation including all of the impairments necessary to meet MHL CTS 2.0 requirements. The direct synthesis solution provides easier, more repeatable test set-ups and lower cost compared to complex sink-based solutions for generating signal impairments.

Option MHD with MHL CTS 2.0 support is available now worldwide. Setups used for MHL CTS 1.2 testing can continue to be used for CTS 2.0.
