13.7.5.2 Search results
To get search results, "Enable" the search. You can minimize, shift or close the search
dialog.
The search results are listed in the search result table and marked in the waveform by
blue lines.
For an introduction to search results, see:
●
Chapter 11.1.2, "Search results", on page 420
●
Chapter 11.4.2, "Display zoom settings", on page 440
Remote commands are listed in Chapter 24.17.8.5, "Search results", on page 1825.
13.7.5.3 Searching CAN FD data
The "Identifier + Data" search supports the search for data bytes of specific value at a
specific location in the data field of a frame. The "Data Pattern" field provides 8 data
bytes to define the pattern. For data fields longer than 8 byte, you can define the posi-
tion where the specified pattern starts.
The following example demonstrates how the data pattern and data position is defined.
To set up the search
1. Set the "Source", the signal to be searched: "SerBus". Select the bus that is config-
ured for CAN FD.
2. Set the search criteria:
a) Select the standard: "CAN FD".
b) Select the search type: "Identifier + Data".
3. In this example, the identifier does not matter. Set the "ID type = Any".
4. Define the data setup as described in the example.
Example: Searching for a specific byte anywhere in the frame
The CAN FD frame has 8 or more data bytes, containing at least one data byte with
value = CB anywhere in the data field.
●
Set "DLC ≥ 8".
●
Set the data pattern: "= CB".
13.7.6 Symbolic trigger, decode and search
The R&S RTO6 can read and apply industry-standard DBC files to the decoded signal
and provides settings for symbolic triggering and symbolic search.
