WaveBPS: Portable Low Level Analog Serial Data Analysis with PicoScope 5204 Oscilloscope, and Navigation Wheel

In the real world, things often go wrong to the point where CAN bus, LIN bus, or FlexRay tools do not show enough information - one has to understand what is going on at a lower level. Intrepid Control Systems, Inc. is proud to introduce WaveBPS, an advanced tool for capturing and analyzing serial data analog waveforms like FlexRay, CAN Bus, UART (J1708, K-Line, SCI, GM CGI), J1850, SPI, I2C or LIN Bus. Besides general purpose monitoring, WaveBPS can quickly capture infrequent or intermittent protocol violations. For example, you can track down the CAN error frames that may occur during a crank event while another application is verifying there are no timing violations on software based LIN implementations.
