Teledyne LeCroy Announces Enhanced Audio Return Channel (eARC) Test Solutions on the quantumdata 980 Series


Provides developers with a way to verify their HDMI 2.1 eARC devices

Elgin, IL, April 12, 2018 – Teledyne LeCroy, the worldwide leader in protocol test solutions, today announced the introduction of a set of test solutions for verifying HDMI 2.1 Enhanced Audio Return Channel (eARC) operation on both eARC Tx and Rx devices. The new test solutions are supported on the 980 48G Protocol Analyzer / Video Generator module for HDMI Testing.

The eARC test solutions covered in this announcement include functional and compliance tests of both eARC transmitting and receiving devices. This initial offering supports nine (9) eARC Tx and nine (9) eARC Rx compliance tests with a commitment to provide the full suite of eARC compliance tests in subsequent releases throughout this year. The module’s eARC functional test features support the emulation of both (either) an eARC Tx or eARC Rx to verify the common mode functions of the eARC device under test. Tests for differential mode will be available in future releases. 

Operation of the eARC compliance tests is simple. The user-selected compliance test suite is initiated through the 980 GUI Manager. Once initiated, the tests run to completion without user interaction. When a test series has been completed, the instrument issues a detailed report that provides pass/fail results for each individual test. Details for each test are provided enabling developers to identify the root cause of a failure. Reports and log files can be viewed through the 980 GUI Manager and can be distributed to colleagues and other subject matter experts for analysis. The 980 Auxiliary Channel Analyzer (ACA) utility captures the eARC common mode transactions during the compliance tests or independently during functional testing. Viewing the eARC transactions enables developers to verify proper operation and investigate compliance test failures.

In addition to the eARC test functions, the quantumdata 980 48G module for HDMI also supports protocol analysis and video generator of HDMI’s new transport mode—Fixed Rate Link (FRL)—for delivering 48Gb/s video across the HDMI link. The addition of this initial set of eARC test solutions is a step toward providing a comprehensive solution for the key HDMI 2.1 features and functions all supported on a single 980 series module, the 980 48G Protocol Analyzer / Video Generator module for HDMI Testing.

The new eARC tests are provided through licensed options available with the 980 48G Protocol Analyzer / Video Generator module. There are separate licenses for functional testing and compliance testing and for source testing and sink testing.
