MSO3000HD-CAN Automotive CAN Serial Bus Trigger and Analysis
Overview
The MSO3000HD-CAN adds CAN (Controller Area Network) protocol triggering, decoding, and search capabilities to your MSO3000HD Series oscilloscope. Once activated, CAN bus traffic appears as decoded frames overlaid directly on the analog waveform — correlating protocol events with the underlying electrical signals in real time.
CAN is the backbone of automotive networking — powertrain, body control, diagnostics (OBD-II), and inter-ECU communication in virtually every vehicle. This option turns your oscilloscope into a protocol-aware diagnostic tool.
Key Features
- Protocol-Aware Triggering — Trigger on specific CAN conditions — frame ID, data content, error frames, remote frames, or overload frames — to isolate the exact bus activity you're investigating.
- Real-Time Frame Decoding — Decoded CAN frames (arbitration ID, DLC, data payload, CRC, acknowledge) display directly on the waveform trace for signal-protocol correlation.
- Deep Memory Protocol Search — Search captured records for specific message IDs, data patterns, or error conditions across the full acquisition memory.
- Error Detection — Identifies CRC, form, stuff, and acknowledge errors — essential for diagnosing intermittent bus failures.
- Software License Activation — License key applied through the instrument menu. No hardware changes, no downtime — enter the key and start decoding.
When You Need This
ECU Development
Trigger on your ECU's arbitration ID to capture only its messages, then verify timing, payload content, and acknowledge behavior against the vehicle network specification.
OBD-II Diagnostics
Capture and decode OBD-II diagnostic messages to verify your device responds correctly to standard requests — essential for emissions compliance.
Compatible Instruments
This option is compatible with all MSO3000HD Series oscilloscopes: MSO3024HD (200 MHz), MSO3034HD (350 MHz), MSO3054HD (500 MHz).

Frequently Asked Questions
What's the difference between CAN and CAN-FD?
Classic CAN supports up to 8 bytes at 1 Mbit/s. CAN-FD extends this to 64 bytes with faster data rates. If your system uses CAN-FD, you need the CAN-FD option — or a bundle for both.
Should I buy this individually or get a bundle?
If you only need CAN, the individual license at $279 is the most economical. The AUTO bundle ($689) adds multiple automotive protocols at a discount. The BND bundle ($1,109) includes every protocol at the deepest discount.
How is this option activated?
You receive a license key after purchase. Enter the key in the instrument's menu under System → Options → Install. The capability is available immediately — no reboot, no hardware modification, no factory service required.
Is the license permanent or subscription-based?
All UNI-T software option licenses are permanent, one-time purchases. Once activated, the option remains available for the life of the instrument. No annual renewals or subscription fees.
