MSO7000X-PWR Advanced Power Analysis and Loop Analysis Option
Overview
The MSO7000X-PWR transforms your MSO7000X Series oscilloscope into a power measurement instrument. Automated switching loss, SOA, ripple, harmonics, THD, efficiency, and power quality analysis.
For power supply, motor drive, inverter, and switching converter design/validation/troubleshooting. Eliminates hours of manual measurement setup.
Key Features
- Switching Loss — Calculates energy per switching transition for MOSFETs, IGBTs. Essential for thermal design and efficiency.
- Safe Operating Area — Plots V×I trajectories against device limits during transients, startup, and faults.
- Ripple Analysis — Output ripple amplitude and frequency content. Identifies sources: switching frequency, ESR, load transients.
- Harmonics and THD — Up to 50th harmonic and total harmonic distortion. Validates IEC 61000-3-2 compliance.
- Efficiency — Input vs. output power for real-time converter efficiency. No external power analyzer needed.
- Software License Activation — License key via instrument menu. No hardware changes.
When You Need This
SMPS Design
Quantify switching losses in a flyback MOSFET. Connect probes, select measurement, get per-cycle loss data automatically.
EV Charging Debug
Charger failing efficiency targets. Compare input/output power in real time, check SOA for device stress.
Compatible Instruments
This option is compatible with all MSO7000X Series oscilloscopes: MSO7104X (1 GHz) and MSO7204X (2 GHz).

Frequently Asked Questions
Do I need special probes?
At least one current probe — UT-CP03 (30A) or UT-CP04 (50A). A differential probe is recommended for floating voltage measurements.
Same as a power analyzer?
Different tools. Oscilloscope PWR excels at time-domain switching analysis (per-cycle loss, SOA, transients). A dedicated power analyzer like UTE310/UTE323 is better for steady-state with higher accuracy. Many engineers use both.
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.
