MSO5000HD-FLEX Automotive FlexRay Serial Bus Trigger and Analysis

MSO5000HD-FLEX – FlexRay Protocol Decode Option

🚘 Decode Deterministic Automotive Networks with the MSO5000HD

The UNI-T MSO5000HD Series oscilloscope combines 12-bit high-resolution analog capture with advanced serial protocol analysis. Designed for automotive systems evolving beyond CAN and LIN, the MSO5000HD-FLEX unlocks support for FlexRay, the time-deterministic bus used in safety-critical applications such as braking systems, steering control, and drive-by-wire.

FlexRay enables much higher speeds and tighter synchronization than CAN, making it ideal for distributed real-time systems—but it also demands rigorous debugging tools. This decode option helps you identify latency, timing jitter, and data corruption with complete waveform correlation.

🔍 Key Capabilities

• Decode FlexRay frame components: sync segment, frame ID, payload, CRC, and cycle counters

• Trigger on specific frame IDs, payload patterns, or timing errors

• Event list generation with full frame metadata

• Search for errors like CRC mismatches or clock drift

• View time-domain alignment between FlexRay and analog phenomena (e.g., voltage dip, ground bounce)

🧠 Benefits of MSO5000HD-FLEX

• Confidence in Safety-Critical Systems
  Spot hard-to-find timing problems and synchronization faults in braking, steering, and ADAS applications.

• Frame-Level Visibility
  Track transmission slots, frame scheduling, and inter-frame spacing across large time bases.

• Cross-Layer Debugging
  Capture timing glitches or voltage swings that would never appear in a pure logic analyzer.

🛠️ Ideal Applications

• Electronic stability programs (ESP) and brake-by-wire systems

• Autonomous vehicle sensor fusion networks

• ECU-to-ECU communication timing verification

• Real-time control systems requiring fault-tolerant networking

• Automotive Tier 1 system integration
