MSO5000HD-1WIRE Embedded Systems 1-Wire Serial Bus Trigger and Analysis
Overview
The MSO5000HD-1WIRE adds 1-Wire protocol triggering, decoding, and search to your MSO5000HD Series oscilloscope — for temperature sensors (DS18B20), iButton devices, EEPROMs, and battery fuel gauges.
Single-wire bidirectional bus where timing is critical. Decodes reset pulses, presence detection, ROM commands, and data bytes on the waveform.
Key Features
- 1-Wire Triggering — Trigger on reset/presence sequences, ROM commands, or data bytes.
- Real-Time Decoding — Decoded transactions with reset, presence, command, and data fields labeled.
- Timing Verification — Read/write slot timing for specification compliance checking.
- ROM ID Display — Shows 64-bit ROM IDs for device identification and enumeration.
- 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
Temperature Sensor Debug
DS18B20 fails to respond intermittently. Decode to verify reset/presence timing and parasitic power.
Device Enumeration
Search algorithm not finding all devices. Decode ROM search commands to find where enumeration diverges.
Compatible Instruments
This option is compatible with all MSO5000HD Series oscilloscopes: MSO5034HD (350 MHz), MSO5054HD (500 MHz), and MSO5104HD (1 GHz).

Frequently Asked Questions
Should I buy this individually or get a bundle?
If you only need 1-Wire, the individual license at $279 is the most economical. The BND bundle ($1,369) 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.
