LeCroy has introduced a FlexRay physical layer test package for its WaveRunner Xi oscilloscope to provide eye diagram mask testing and physical layer measurement parameters for the in-car comms protocol.

Integrating eye diagram testing, physical layer measurements, protocol trigger and decode means that automotive engineers can more-effectively debug the FlexRay protocol.

The test package supports 10, 5 and 2.5Mbit/s standard data rates and can perform eye diagram mask testing on live acquisitions of saved waveforms. The test can be configured to indicate mask failures and stop when a failure occurs, letting the user reference the failing bit and the decoded protocol data to know exactly where the problem occurs.

Beyond the eye diagram test, four FlexRay specific physical layer timing parameters are built in to quantify how signals propagate along the communication channel.
