Application Note: Debugging SENT Automotive Buses with an Oscilloscope

May 21, 2021
Simplify SENT Sensor Bus Troubleshooting
SENT bus (SAE J2716) is a cost-effective, precise way to transmit sensor data to ECUs, with key advantages over analog PWM. But while the pulse-width encoding used in the standard is reliable, it is very difficult to decode by hand. Adding automated decoding and triggering to your oscilloscope greatly simplifies troubleshooting.

This application note:

  • Gives a brief orientation on the physical layer and packet structures of SENT
  • Explains how to set up decoding on an oscilloscope equipped with SENT decoding
