Automotive protocols

Trigger and decode oscilloscope software package

Key Facts

Symbolic decoding for CAN, CAN-FD, CAN-XL, LIN, FlexRay, SENT and CXPI buses, including industry-standard CAN DBC and FIBEX file support
Time-correlated serial decoding with the captured waveform for quick insights
Easy visualization of bus content with color-coded bus frames and a dedicated decode table
Flexible trigger isolates the start of frame, identifier, data, symbol and various error conditions such as CRC errors, timing or pulse period errors
Powerful search and navigation capability of bus content such as start of frame, frame type, identifier, data and error conditions

Automotive trigger & decode

R&S®RTO6/RTP oscilloscopes can trigger and decode of CAN, CAN-FD, LIN, FlexRay™ and CXPI buses. R&S®MXO oscilloscopes support CAN, CAN-FD, CAN-XL, LIN and SENT. Decoding live waveforms is time-correlated with the captured waveform and the bus frames. Each frame is color-coded to give users the ability to quickly distinguish frame types. The data can also be viewed in a table with timing information and all relevant data conveniently displayed. Raw data can be translated into application specific information using CAN DBC or FIBEX file imports. Errors within the bus are efficiently and reliably isolated with the hardware-accelerated trigger architecture.

Features & benefits

Fast bus setup

Bus setup in seconds with the app button

Starting from the app button, any automotive protocol can be configured in a few steps. Set the appropriate bus to be decoded, connect and select the channels along with the right threshold levels and decoding beings instantly.

**Clear and quick selection of the right automotive bus via app cockpit dialog**

Color coded bus display

Frame types as color-coded bus signals

Users can analyze decoded bus frames with the color-coded frame types overlaid over the analog waveform. Address and data content can be displayed in hex, bin or ASCII formats. Flexible screen setup via the R&S®SmartGrid gives the best overview of decoded data. All decoded information can also be displayed in a concise table.

Strong trigger capability

Trigger on frame types such as

The protocol-aware trigger lets users reliably isolate specific protocol based events and errors. The high acquisition rates of R&S oscilloscopes makes them ideal for finding errors quickly and triggering on specific protocol fields such as CAN Identifier, LIN wakeup frame or various error conditions.

Search and navigate

Powerful search and navigation of recorded acquisitions

Comprehensive search functions simplify the analysis of long signal sequences. Users can use different criteria (specific Identifiers or a certain error conditions) to search the decoded data. All detected events are shown in a table with timestamps. Zooming into the decoded data to move through the table makes navigating through events extremely easy.
