LeCroy Extends Automotive Testing with Physical Layer Test Tool

LeCroy has the only solution which offers advanced triggering, protocol decoding and physical layer test in a single instrument. Other oscilloscope-based FlexRay products offer either advanced protocol triggering with decode but no physical layer test, or decode and eye diagrams but no FlexRay measurement parameters and only a simple trigger.

Integrating eye diagram testing, physical layer measurements, protocol trigger and decode means that automotive engineers can now, with a single instrument, effectively debug the FlexRay protocol and efficiently verify signal integrity as well. The WaveRunner Xi oscilloscope’s advanced FlexRay tools; trigger and decode tools for CAN, LIN, I2C, SPI UART; and Mixed Signal Oscilloscope options, make it a powerful, well-rounded oscilloscope for automotive embedded controller design and debug.

LeCroy’s FlexRay physical layer solution supports 10 Mb/s, 5 Mb/s and 2.5 Mb/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. These parameters measure Propagation Delay, Asymmetric Delay, Truncation and Jitter in accordance with the FlexRay physical layer specification. For further insight, LeCroy’s statistical tools with histogram, track and trend capabilities show how the communication channel behaves over time.
