UPO6000LP-PWR Power Analysis Option (advanced power analysis and three-phase power analysis)
Overview
The UPO6000LP-PWR turns your UPO6000LP Series oscilloscope into a switching-power analyzer. Choose an analysis, follow the on-screen wiring diagram for the voltage and current probes, and the scope configures its channels, runs the measurement and reports results as waveforms, a result table and live parameter statistics. Twelve analyses cover the whole converter — AC input, the switching device, the control loop and the output — and 8-channel models add three-phase power analysis.
Why it matters: efficiency, thermal margin and reliability are decided in the switching transitions. Measuring switching loss, Rds(on) or SOA by hand means exporting waveforms and doing the math offline; the option does it on the instrument, and the 12-bit ADC gives the vertical resolution to see small conduction voltages beside large switching ones.
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
- Input Analysis — Power quality (RMS and peak voltage and current, crest factors, real, reactive and apparent power, power factor and phase angle), harmonics to the 40th with pass/fail against IEC 61000-3-2 Class A/B/C/D, and inrush (surge) current.
- Switching Device Analysis — Switching loss and energy for turn-on, conduction and turn-off (using measured waveforms, Rds(on) or Vce(sat) models), Rds(on), dV/dt and dI/dt slew rate, and a safe-operating-area mask test with custom, importable masks.
- Output and Loop Analysis — Output ripple, modulation analysis of the control pulse (width, duty cycle, period, frequency, edges), transient response to load steps, and startup/shutdown time.
- Efficiency and Three-Phase — Input-to-output efficiency, plus three-phase power analysis with power quality, harmonics, ripple, efficiency and DQ0 analysis and a space-vector display on 8-channel models.
- 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:
- SMPS and Converter Design — Quantify turn-on, conduction and turn-off loss in a MOSFET or IGBT, check it stays inside its SOA at startup, and confirm efficiency at every load point.
- Motor Drives and Inverters — On an 8-channel model, measure all three phases of an EV drive, industrial motor or solar inverter at once for power quality, harmonics and DQ0 analysis.
Compatibility
This option is positioned for the 8-channel UPO6000LP Series models: UPO6038LP (350 MHz), UPO6058LP (500 MHz) and UPO6108LP (1 GHz), which have the channels to measure three voltages and three currents together for three-phase analysis. Power analysis features are delivered in the instrument firmware, so keep the oscilloscope updated to the latest UNI-T release.
Working on power-supply design with a 4-channel UPO6000LP? UPO6000LP-GEN adds Bode plot loop-stability and PSRR sweeps using the built-in generator.
The same capability is offered on other UNI-T oscilloscope families: MSO2000X, MSO3000HD, MSO5000HD, MSO7000X, MSO8000HD, UPO7000L.
Frequently Asked Questions
Do I need special probes?
Yes — power analysis needs a current probe and, for floating or line-referenced measurements, a differential voltage probe. The on-screen wiring diagram for each analysis shows exactly where each probe connects. Efficiency and three-phase analysis need more than one voltage/current pair.
How is this option activated?
Buy the option key from your UNI-T distributor, then enter the key and the oscilloscope's serial number on the License Activation page of the UNI-T website to generate a license file. Copy the file to the root of a USB drive and activate it under Utility > Options. The Options screen then lists the option as Activated, with a duration of Permanent.
Can I try it first, and is the license permanent?
Yes to both. Every UPO6000LP option includes a 540-hour trial on the instrument, so you can prove it on your own hardware before you buy. Once activated, the license is permanent for the life of the oscilloscope — no subscriptions, no renewals and no expiration.
