REPLACEMENT PRODUCT: This product has been replaced by package M9240AUTB. This replacement enables multiple software options at once.
CXPI (Clock Extension Peripheral Interface) is the next-generation automotive communication protocol intended to reduce the number and weight of wiring harnesses by making multiplexing possible even in advanced, multifunction HMI (human machine interface) automotive systems. In many cases, CXPI is an alternative serial bus used in place of many of today’s LIN serial bus applications for automotive body control.
Keysight’s CXPI option (M9240CXPA) for M924XA Series oscilloscopes provides decoding of standard and long CXPI frames, and also offers extensive triggering selections, including the ability to trigger on various error conditions that can accelerate the engineer’s efficiency in debugging this bus.
Keysight’s M924XA Series oscilloscopes can display captured data from multiple buses in a time-interleaved “lister” display. This allows correlation of data being passed through gateways, such as CAN to CXPI.
This option works with M9241A, M9242A and M9243A PXIe modular oscilloscopes.
