Serial Bus Trigger [ENHANCED]
The instrument has trigger features that capture the following ten types of serial bus signals. Of the ten types,
FlexRay, CAN, CAN FD, LIN, CXPI, SENT, UART, I2C, and SPI bus triggers are options available only for
4-channel models.
The FlexRay bus trigger is used to capture FlexRay bus signals. FlexRay is an automotive LAN communication
protocol established by the FlexRay Consortium.
The CAN bus trigger is used to capture CAN bus signals.
Controller Area Network (CAN) is a serial communication protocol that has been standardized internationally
by the ISO (International Organization for Standardization). The instrument is equipped with a symbolic trigger
function.*
* Using YOKOGAWA free software, you can convert a CANdb file (.dbc) to a physical value/symbol definition file,
(.sbl), load the file into the instrument, and use it as a set of trigger conditions. You can obtain the free software
from the YOKOGAWA website (http://www.yokogawa.com/tm/).
CANdb files (.dbc) are signal definition database files created using the CANdb or CANdb++ software
produced by Vector Informatik.
The CAN FD bus trigger is used to capture CAN FD bus signals.
CAN FD is an abbreviation for CAN with Flexible Data Rate. It is based on CAN and supports high-speed data-
phase transfer rates. The length of data that can be embedded in a single Data Field is expanded to up to 64
bytes, and the CRC generator polynomial is also expanded. As with CAN, symbolic triggering is possible.
The LIN bus trigger is used to capture LIN bus signals.
A Local Interconnect Network (LIN) is a serial communication protocol mainly used in automobiles.
The CXPI bus trigger is used to capture CXPI bus signals.
CXPI is an acronym for Clock Extension Peripheral Interface and is an on-vehicle LAN communication protocol
used for human machine interface (HMI) and other interfaces of automotive electronic systems.
The SENT bus trigger is used to capture SENT signals.
SENT is an abbreviation for Single Edge Nibble Transmission. It is a point-to-point unidirectional serial
communication protocol. The instrument supports SAE J2716 ARP2016 and earlier versions.
The UART trigger is used to capture UART signals.
A Universal Asynchronous Receiver Transmitter (UART) is an integrated circuit that performs serial-to-parallel
conversion and parallel-to-serial conversion. UART signals are generally used in inter-device communication
such as with EIA RS-232.
