Solve: Integrated hardware-based serial decoding and triggering

(option) makes easy work of low speed serial buses

Keysight InniiVision oscilloscopes, including the new 3000T X-Series, use

hardware-based serial protocol decoding. Some other vendors use software

post-processing techniques to decode serial packets⁄ frames, and therefore have slow

waveform and decode capture rates and could miss critical events and errors due to a

long dead-time. Faster decoding with hardware-based technology enhances the

probability of capturing infrequent serial communication errors.

After capturing serial bus communication, you can easily perform a search operation

based on specic criteria and then quickly navigate to bytes/frames of serial data that

satisfy that search criteria. The 3000T X-Series can decode two serial buses

simultaneously using hardware based decoding, and display the captured data in a time

interleaved “lister” display.

Serial protocol decoding can be used simultaneously with segmented memory and

Zone touch triggering. The 3000T X-Series has the most decode/trigger

options in this class of instrument including: I²C, SPI, RS232/422/485/UART, CAN,

CAN-FD, CAN-dbc, LIN, SENT, FlexRay, MIL-STD 1553, ARINC 429, and I²S.

SERIAL DECODE AND

TRIGGER OPTIONS

The 3000T X-Series supports a

range of different serial decode and

trigger options including:

– I

– SPI (2/3/4 wire)

– RS232/422/485/UART

– CAN

– CAN-dbc

– CAN-FD

– LIN

– SENT

– FlexRay

– MIL-STD 1553

– ARINC 429

– I

Solve: Segmented smart memory combined with protocol analysis

enables insights over long periods of time

Segmented memory works in conjunction with any of the optional serial protocol

decodes. For example, by setting the trigger condition to “SENT serial bus error,”

segmented memory captures and stores only SENT pulse period error packets and

stitches together each segment for easy viewing of the decoded data in the lister. You

can quickly compare time tags to discover time intervals between errors.

insight to the serial bus.
