Teledyne LeCroy’s LIN trigger, decode and measurement toolsets permit isolation of specific bit-level data patterns in one or more data bytes, e.g., data location in bits 18-26 spanning data bytes 2 and 3. This provides significant advantages in isolating the exact information or behavior you need.

Teledyne LeCroy simplifies the analysis of the complex FlexRay protocol. Powerful physical layer test analysis functions are provided, SI voting is supported, and important timing parameters, such as propagation delay, asymmetric delay, truncation, and jitter provide detailed information on how signals propagate along the channel.

Teledyne LeCroy’s configurable Manchester decode option enables flexible, user-definable protocol decoding of serial buses such as PSI5. Physical layer specifications (e.g., bit rate, idle state, polarity) are easily defined for decoding of every bit transmitted on the bus. Higher level decode can be done by configuring bits to words and then words to packets.
