MSO3000HD-CAN-FD – CAN FD Protocol Decode Option

🚀 Analyze Next-Generation Vehicle Networks with CAN FD Decoding

The MSO3000HD-CAN-FD software unlock adds triggering, decoding, and analysis support for CAN FD (Flexible Data Rate) to your UNI-T MSO3000HD Series oscilloscope. CAN FD extends the classic CAN protocol with faster data rates and longer payloads—allowing modern ECUs to transmit more data, more quickly, with greater timing precision.

This upgrade is critical for engineers working in advanced driver-assistance systems (ADAS), electric vehicles, powertrain controls, and high-bandwidth automotive domains.

✅ Standard Protocols (No License Required)

The following protocols are always included with your MSO3000HD oscilloscope:

RS-232 / UART
I²C
SPI

🧩 Classic CAN decoding requires the MSO3000HD-CAN option.

🔓 What You Unlock with MSO3000HD-CAN-FD

Feature	Description & Application Example
High-Speed Data Decode	Supports up to 64-byte payloads at elevated bit rates. 📌 Used for large sensor or actuator messages in EVs.
Arbitration/Data Phase View	Distinguishes low-speed arbitration and high-speed data phases. 📌 Validates ISO and non-ISO frames.
Trigger on Extended IDs or Errors	Target specific message IDs, control bits, or bus faults. 📌 Capture startup glitches or rare fault events.
Real-Time Frame Overlay	View protocol decode live atop analog or digital signals. 📌 Helps debug both electrical and logical issues together.
Exportable Event Table	Save time-stamped frame logs with full decode. 📌 Used for compliance, validation, or system debug.

🧠 Real-World Use Cases

✅ Battery Management Systems (BMS)

Decode multi-byte voltage, temperature, and status messages between control units. Validate CRC integrity and timing on high-speed messages.

✅ ADAS Control Networks

Monitor radar and camera data on high-bandwidth CAN FD channels. Trigger on message frequency or payload changes tied to system events.

✅ Vehicle Domain Controller Debug

Use time-correlated decoding to trace CAN FD message flow between powertrain, chassis, and infotainment domains—especially in mixed-protocol gateways.

✅ In-Plant and Diagnostic Tools

Validate proper communication across all CAN FD-capable ECUs before final integration or delivery. Identify frame rejections, incomplete handshakes, or encoding issues.
