MSO8000HD-SMBUS Embedded Serial Bus SMBus Option
Overview
The MSO8000HD-SMBUS adds SMBus (System Management Bus) protocol decode to your MSO8000HD Series oscilloscope — I2C-derived protocol for power management, battery management, temperature monitoring, and fan control.
SMBus adds packet error checking (PEC), host notify, alert response, and specific commands over the I2C layer. Essential for PMIC and battery charger development.
Key Features
- SMBus Decoding — Quick Command, Send/Receive Byte, Read/Write Word, Block transfers, Process Call.
- PEC Verification — Validates Packet Error Checking CRC — not available in standard I2C decode.
- Host Notify and Alert — Decodes SMBus alert protocol and host notification events.
- Triggering — Trigger on command types, data values, and PEC errors.
- Software License Activation — License key applied through the instrument menu. No hardware changes, no downtime — enter the key and start decoding.

Frequently Asked Questions
Can I use I2C decode instead?
I2C shows raw bytes but misses SMBus-specific features (PEC, Quick Commands, Block transfers, Alert Response). If your design uses SMBus features, you need this option.
Should I buy this individually or get a bundle?
If you only need SMBus, the individual license at $999 is the most economical. The BND bundle ($5,399) 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.
