SENTbus D   High-resolution SENT sensor and ECU message frames are intuitively decoded on the waveform, provided in an interactive table, and payload content search tools make debugging fast and effective.
SENTbus TD   The SENT Trigger Decode (TD) solution provides high performance triggers and transparent color-coded decode overlays, protocol tables, and search capabilities.
SENTbus TDME   The SENT Trigger, Decode, Measure/Graph and Physical Layer (TDME) solution provides high performance triggers, transparent color-coded decode overlays, protocol tables, and search capabilities, Measure/Graph capability with automated measurement and graphing tools, and Eye Diagram capability for physical layer signal assessment and debug.

The Single Edge Nibble Transmission encoding scheme, SENT, SAE J2716, is intended for use in applications where high resolution sensor data needs to be communicated from a sensor to an Engine Control Unit (ECU). It is intended as a replacement for the lower resolution methods of 10 bit A/D's and PWM and a simpler low cost alternative to CAN or LIN. The implementation assumes that the sensor is a smart sensor containing a microprocessor or dedicated logic device (ASIC) to create the signal.

SENT is a unidirectional communications scheme from sensor / transmitting device to controller / receiving device which does not include a coordination signal from the controller / receiving device. The sensor signal is transmitted as a series of pulses with data encoded as falling to falling edge periods.
