Rohde & Schwarz presents new software for three-phase power analysis on MXO series oscilloscopes

Rohde & Schwarz presents new software for three-phase power analysis on MXO series oscilloscopes With the new R&S MXO-K333 3-phase power analysis software option, Rohde & Schwarz brings power analyzer-style insights directly to its MXO series oscilloscopes. Designed for engineers developing and debugging three-phase AC systems, the option delivers more than numerical results alone. It combines key power measurements with full waveform visibility, enabling users to quickly correlate power behavior with real signal events and troubleshoot issues faster.

The R&S MXO-K333 software option provides comprehensive measurement functions for analyzing three-phase power systems.

Rohde & Schwarz has introduced the new R&S MXO-K333 software option for three-phase power analysis on its MXO series oscilloscopes. The software adds in-depth measurement and analysis functions for testing and debugging three phase power systems, drives and inverters.

Available for all four and eight channel models of the R&S MXO 3 , R&S MXO 4 , R&S MXO 5 and R&S MXO 5C oscilloscopes, it supports the analysis of voltage and current signals in three-phase AC systems. This innovative test solution keeps the captured waveforms visible during measurement, allowing engineers to review power values and check transient behavior in the same instrument. Other oscilloscope functions such as math, spectrum analysis, measurement tracking and zone trigger remain available for further analysis.

A guided setup wizard assigns the oscilloscope channels to the voltage and current probes used for the three-phase analysis. It verifies the wiring and supports common two-wire, three-wire and four-wire configurations (2V2A, 3V3A and 3VN3A). After setup, the software provides cycle-by-cycle calculations for RMS values, power factor, active power, reactive power and total power. By defining the input and output configuration, users can also calculate the system's three-phase efficiency. Additional analysis views include phasor display, harmonic analysis and THD measurements in line with IEC 61000-3-2 and MIL-STD-1399.

As an oscilloscope-based solution, the R&S MXO-K333 enables engineers to correlate three-phase power results directly with the underlying voltage and current waveforms in real time. This is especially valuable during R&D and debugging, when power behavior often must be analyzed alongside switching events, transients, control signals and communication activity. Users can combine the three-phase analysis with inherent MXO capabilities such as advanced triggering, FFT, automated measurements, track functions and protocol decoding. This allows engineers to move from power measurement to root-cause investigation in a single instrument.

The R&S MXO-K333 3-phase power analysis oscilloscope software is now available from Rohde & Schwarz.
