i The CLX000 is able to log up to around 800-1000 frames without message-loss. The CANedge is designed for lossless logging at any busload and has been used in various use cases to record 3000+ frames/second (1500+ per channel). In practice, most CAN bus applications broadcast between 500-1500 frames/second.
