Sensors equipped in automobiles are becoming more accurate and more efficient in order to accomplish advanced regulation. These data are sent in analog method (voltage level and pulse modulation) to ECU but accuracy degradation in data transmission circuit from A/D conversion errors in ECU, increasing numbers of wire harness from multifunction sensors, increasing electromagnetic noise from motorization has been major issues. Recent years, in order to resolve these issues, a digital method SENT (Single Edge Nibble Transmission, SAE-J2716) communication is beginning to be used for high-accuracy sensors. Highly accurate and reliable data transmission can be achieved at low cost by using SENT communication equipped with error detection and capability to transmit highly accurate multiple data through single signal line. SENT communication is becoming rapidly popular in angle sensor used in steering and air flow sensors. YOKOGAWA will support construction and verification of entire communication system and evaluation of single unit IC supporting SENT through DLM2000/DLM4000 and DL850EV.
ScopeCorder DL850E combines a mixed signal oscilloscope and portable data acquisition recorder into a modular platform designed to capture both high-speed transients and low speed trends. Using flexible modular I/O with built-in signal conditioning, precisely measure electrical, physical sensor signals and CAN/CAN FD/LIN/SENT serial bus for applications ranging from R&D research to in-vehicle data logging.
