Automotive protocols

Automotive Trigger & Decode

R&S®RTO6/RTP oscilloscopes support trigger and decode of CAN, CAN-FD, LIN, FlexRay™ and CXPI buses. Decoding of the live waveform happens in seconds, which is all time correlated with the captured waveform and the bus frames. Each frame is colour-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. Additionally, the raw data can be translated into application specific info using CAN DBC or FIBEX file imports. Errors within the bus are isolated efficiently and reliably using the hardware-accelerated trigger architecture. 

Fast bus setup

Bus setup in seconds with the App button

Starting from the apps button, it only takes a few steps to configure any automotive protocol. Set the appropriate bus to decode, the relevant channels are connected and selected and the right threshold levels are set, decoding beings instantaneously. 

Color coded bus display

Frame types as color-coded bus signals 

Users can analyse the decoded bus frames either 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 users the best overview of the decoded data. Additionally, all decoded information can be displayed in a concise table.  

Strong trigger capability

Trigger on frame types such as 

The protocol-aware trigger let users to reliably isolate specific protocol-based events and errors. Thanks to the high acquisition rates of R&S oscilloscopes, it 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 capabilites on recorded acquisitions

Comprehensive search functions simplify the analysis of long signal sequences. Users can search the decoded data based on different criteria, such as specific Identifiers or a certain error condition. All detected events are shown in a table with timestamps. Applying a zoom function over the decoded data to move through the table makes navigating through the events extremely easy.
