    Debugging SENT Automotive Buses with an Oscilloscope

    Jan. 15, 2020
    The SENT bus is used in automotive sensors to transmit high-resolution measurements to electronic control units. Decoding the SENT bus by looking at the signals can be difficult, especially due to the pulse-width encoding scheme used in the standard.

    SENT buses are well-defined and are designed to be robust and easy to integrate, but communications can be affected by noise, board layout, reset issues, and subtle differences in implementations. These can sometimes result in bus errors and system malfunctions. Learn how to set up decoding on an oscilloscope equipped with SENT decoding, as well as how to interpret fast and slow channel packet data. See what triggering and searching options are available on an oscilloscope equipped with SENT serial triggering and analysis.
