FlexRay Trigger (Option)

MSO5000-E can trigger on the specified frame, symbol, error, or position of the
FlexRay bus.
FlexRay is a type of differential serial bus configured with three consecutive
segments (i.g. header, payload, and trailer). Its data transmission rate is up to 10
Mb/s. Each frame contains a static segment and a dynamic segment, and ends with
the bus idle time.
Its format is as shown in the figure below.
