Where this fits
- Filter and bookmark trace rows to focus on relevant recorded traffic.
- Inspect unknown frame IDs, decoded signal statistics, and plots.
- Configure channels and DBC mappings for multi-source sessions.
Offline CAN log analysis
Understand the signals in your recorded CAN traffic.
Open ASC or BLF recordings, map your DBC definitions, and inspect decoded signals on your own machine. Log analysis and German–English translation are both included in the $34 DBC Utility Pro license.
Illustrative example · Recorded traffic → decoded signal
ASC / BLF log+ DBC definitions→ Signal plot
Illustrative values, not an app capture or measured result. Use your DBC mapping to interpret recorded frames.
Typical workflow
- Open an ASC or BLF file in Log Analyzer.
- Map the required DBC files and configure channels.
- Filter the trace, plot decoded signals, and review statistics or unknown IDs.
Helpful next pages
Know the scope before you buy.
v2.0.3 analyses recorded ASC and BLF files with your DBC mappings. Signal export and log encoding are not included. Correct decoding depends on the definitions and channel mappings you supply.
Log and DBC analysis run locally without uploading your files. Internet access is needed for checkout, downloads, license checks, updates, and support.
