The RTO-K4 option for FlexRay interfaces from Rohde & Schwarz is for use with the company's RTO oscilloscopes. It provides a trigger and decoding option for the FlexRay serial communications interface
In the automotive industry, this interface type must be tested for errors before it is put into operation. The option makes this job easier by triggering on FlexRay-specific protocol data. The acquired waveforms are then decoded into readable protocol content. The hardware-based trigger system provides high acquisition rates to ensure fast debugging.
A range of protocol-specific trigger conditions allows for flexible testing and debugging approaches. Test dialogs are intuitive because explanatory graphics and links to other settings facilitate configuration. To present measurement results in a clear-cut and straightforward manner, protocol details in the measured waveform are color-coded and protocol data is compiled in tables.
