When equipped with the CXPI option, the DLM Series oscilloscopes will decode and display CXPI frames in real time, produce a list display of the decode results, and allow highlighting of points on the list for display in a zoom window.
February 26, 2018 - CXPI – Clock Extension Peripheral Interface – is an automotive serial bus interface that is designed to provide an optimized solution in applications previously served by the established CAN and LIN bus systems, which until now have been the main interfaces used for in-vehicle communications...
CXPI was standardized in 2015 under SAE J3076 as a communications bus for diverse automotive applications. The bus uses pulse-width modulation to transmit data over a single wire at 20 kbit/s. The characters used are based on UART.
CXPI has the CSMA/CR system (event initiate system) built into the polling system of LIN. It has reduced the number of the parts needed for the clock side of the design because a data and a clock signal can transmit at the same time via PWM.
When equipped with the CXPI option, the DLM Series oscilloscopes will decode and display CXPI frames in real time, produce a list display of the decode results, and allow highlighting of points on the list for display in a zoom window. After the acquisition, dedicated parts of the display can be searched for a number of specified conditions.
An auto setup feature can be used to analyze the input signals, set the time and voltage axes automatically along with various trigger settings such as threshold levels, bit rates and trigger type, and then display the decoded result.
Yokogawa’s DLM2000 and DLM4000 mixed-signal oscilloscopes are designed for a range of measurement and analysis tasks in the electronics, automotive and mechatronics sectors.
