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. The option is enabled by a software license keyed to the oscilloscope's serial number and is permanent for the life of the instrument.
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.
- Lifetime License Activation — activate once, owned for the life of the instrument. No subscriptions, no renewals, no maintenance fees.
When You Need This Option
The option fits the following workflows:
- Battery Management Debug — Smart battery charger communicating with fuel gauge over SMBus. Verify state-of-charge reads and PEC.
- Server BMC Development — BMC reads sensors and controls fans over SMBus. Verify polling intervals and alerts.
Compatibility
This option is compatible with the MSO8000HD Series: MSO8804HD (8 GHz).
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 covers exactly that protocol. The BND bundle includes every protocol in the series.
How is this option activated?
The option is enabled by a software license keyed to the oscilloscope's serial number. After purchase, the license is registered on the UNI-T website to generate the license file, which is then loaded onto the instrument from a USB drive through the option-install menu. Refer to the oscilloscope's user manual for the step-by-step procedure.
Is the license permanent, or does it require renewal?
The license is permanent — a one-time purchase that stays active for the life of the instrument. No subscriptions, no annual renewals, and no expiration.
