SANTA ROSA, Calif., May 3, 2016
Keysight Technologies, Inc. (NYSE: KEYS) today announced the clock extension peripheral interface (CXPI) decoding and triggering options for its InfiniiVision 3000T and 4000 X-Series oscilloscopes. These are the only oscilloscopes available today that can decode and trigger on the CXPI bus. These new capabilities improve engineers' efficiency in debugging the physical layer of CXPI serial buses, which are used primarily in automotive applications.
CXPI is the next-generation, higher-performance serial bus protocol for automotive body control applications. Although the local interconnect network (LIN) is the primary bus used today for body control, it is often difficult to achieve sufficient performance and reliability in human machine interface (HMI) applications that require responsiveness. For this reason, the CXPI bus will eventually replace many of today's LIN bus applications. The CXPI protocol provides some features of the controller area network (CAN) protocol, such as non-destruction arbitration, as well as extension error detection and recovery, implemented on a UART-based data link.
Using an oscilloscope to test and debug the signal integrity (physical layer) of CXPI signals is critical for ensuring error-free transmission of data. Keysight's new CXPI triggering and decode capabilities in the InfiniiVision 3000T and 4000 X-Series oscilloscopes will rely on hardware-based decoding to enable the industry's fastest decode update rates. Faster waveform and decode update rates increase the scope's probability of capturing random and infrequent errors. With these new options, the InfiniiVision oscilloscopes can decode and trigger on specific errors (optionally filtered by frame ID) such as CRC errors, parity bit errors, data length errors, inter-byte space errors, inter-frame space errors, sample errors and framing errors. Detection and elimination of bus errors during the design phase is crucial for automotive safety.
The new Keysight CXPI trigger and decode options will be available for purchase in July. Additional information about Keysight automotive testing using oscilloscopes is available at www.keysight.com/find/scopes-auto. Product images are available at www.keysight.com/find/DSOXCXPI_images.
Keysight's complete oscilloscope portfolio includes instruments with a variety of form factors with bandwidths from 20 MHz to 90 GHz.
The CXPI specification (SAE J3076_201510) from SAE International is available at www.sae.org.
