15 Analyzing and Searching Serial Bus Signals
The instrument can decode frames, fields, and other information from the waveform displayed on the screen.
Then, it can display the decoded results along with the waveform on the screen or display a list of detailed
decoded results.
If you set search conditions and perform searches, the waveform can be displayed expanded, with the detected
frame’s or field’s first data byte at the center of the window.
The instrument can perform waveform analysis and searching on up to four serial bus signals (Serial Bus1(S1),
Serial Bus2(S2), Serial Bus3(S3), and Serial Bus4(S4)). The instrument can search up to 50000 points on the
selected serial bus signal.
* SERIAL BUS1(S1) only for 2-channel models

Turning the Analysis and Search Feature On or Off (Display)
Set whether or not to perform serial bus signal analysis and searching. If you turn this feature on, the instrument
displays the decoded field values at the bottom of the screen.
• OFF: Does not perform serial bus signal analysis and searching
• ON: Performs serial bus signal analysis and searching
Number of Analyzable and Searchable Frames or Data Bytes
The maximum number of analyzable and searchable frames or data bytes varies depending on the serial bus
type as follows:
FlexRay
5000 frames
CXPI
10000 frames
CAN FD
Up to 50000 frames
CAN/LIN/SENT
100000 frames
UART/I
2
C/SPI/User Define
300000 bytes
