M9240SNSA 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 M9240SNSA
SENT software option for the M924XA 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 M924XA Series 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.
M9240CXPA 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 M9240CXPA CXPI software 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.
M9240AROA 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 M924XA PXIe modular 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.
M9240NRZA user-definable Manchester and NRZ trigger and
analysis
Keysight’s Manchester and NRZ decode and trigger software supports user-defined
protocols, offering flexibility and preventing the need to define multiple specific protocol
decoding and triggering. This trigger and decode software application is geared toward
automotive customers, who commonly use Manchester and NRZ encoded buses (ex:
Profibus PA, DALI, PSI5, etc.).
