MSO8000HD-PWR Advanced Power Analysis Option
Overview
MSO8000HD-PWR adds automated power analysis to the MSO8604HD and MSO8504HD, the two MSO8000HD models with a 1 MΩ input path specified to 500 MHz. It measures power quality, inrush current, harmonics, switching loss, safe operating area (SOA), start-up and shut-down timing, modulation, ripple, efficiency, Rds(on), power-supply sequencing, slew rate (dv/dt and di/dt), control-loop response (Bode plot) and power-supply rejection ratio (PSRR).
For power-supply, converter, inverter, motor-drive and power-delivery design and validation. 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
- Switching Loss and SOA — Energy per switching transition and V×I trajectories against device limits during start-up, transients and faults.
- Rds(on), Slew Rate and Modulation — Conduction resistance, dv/dt and di/dt, and modulation analysis on the switching node.
- Ripple, Inrush and Sequencing — Rail ripple, inrush current, start-up and shut-down timing and multi-rail power-supply sequencing.
- Power Quality, Harmonics and Efficiency — Input power quality and harmonics, with input-to-output efficiency.
- Control-Loop Response and PSRR — Bode-plot loop response and power-supply rejection ratio.
- Lifetime License Activation — Activate once, owned for the life of the instrument. No subscriptions or renewals.
Compatibility
Compatible with the MSO8604HD (6 GHz) and MSO8504HD (5 GHz). The same capability is offered on other UNI-T oscilloscope families: MSO2000X, MSO3000HD, MSO3000X, MSO5000HD, MSO7000X, UPO2000HD, UPO7000L.
Frequently Asked Questions
Which probes do I need?
A current probe and, for floating measurements, a high-voltage differential probe, both on the 1 MΩ input path. For the MSO8000HD: UT-P4150, UT-P4030D or UT-P4500 current probes; UT-P30 through UT-P36 high-voltage differential probes; and the UT-PR2060 power rail probe for low-voltage rail ripple.
Is this the same as a power analyzer?
Different tools. Oscilloscope power analysis excels at time-domain switching work — per-cycle loss, SOA, transients and loop response. A dedicated power analyzer is better for steady-state measurement at higher accuracy. Many engineers use both.
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.
