P9240SNSA SENT (single edge nibble transmission) trigger and

analysis

The SENT (single edge nibble transmission) is a point-to-point serial bus that interfaces

sensors to ECUs and is used primarily in automotive applications. Keysight’s P9240SNSA

SENT software option for the P924xA Series oscilloscopes provides decoding of fast and

slow channel serial data and also offers extensive triggering selections, including the

ability to trigger on various error conditions that can accelerate efficiency in debugging

this bus.

Keysight’s P924xA Streamline USB oscilloscopes can display captured data from

multiple buses in a time-interleaved “lister” display. Sometimes it may be necessary to

correlate data from one serial bus to another, such as CAN to SENT.

P9240CXPA CXPI trigger and decode

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 P9240CXPA CXPI software for P924xA 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 P924xA 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.

P9240AROA MIL-STD 1553 and ARINC 429 aerial triggering and

analysis

The MIL-STD 1553 serial bus is primarily used to interconnect avionics equipment in

military aircrafts. This bus is based on tri-level signaling (high, low and idle) and requires

dual-threshold triggering, which the P924xA Streamline Series USB oscilloscopes

support. This bus is also implemented as a redundant multi-lane bus (dual-bus analysis),

which is also supported.

The ARINC 429 serial bus is used to interconnect avionics equipment in civilian aircrafts.

This bus is also based on tri-level signaling (high, low and null) and requires dual-

threshold triggering. Since ARINC 429 is a point-to-point bus, multi-lane analysis is also

required to capture both send and receive data.
