Rohde & Schwarz has expanded the capabilities of its MXO series oscilloscopes with the introduction of the R&S MXO-K333 three-phase power analysis software, enabling engineers to perform advanced power analysis directly on their oscilloscopes. The new software combines comprehensive three-phase power measurements with real-time waveform visibility, helping engineers accelerate testing, debugging and validation of AC power systems, motor drives and inverters.
Designed for engineers working on power electronics and electrical systems, the R&S MXO-K333 transforms compatible MXO oscilloscopes into powerful power analysis tools by integrating waveform visualization with detailed electrical measurements. Unlike conventional power analyzers that primarily display numerical values, the software allows users to correlate power measurements with live voltage and current waveforms, making it easier to identify switching events, transient behavior and system anomalies.
The power analysis software is available for all four- and eight-channel models of the Rohde & Schwarz MXO 3, MXO 4, MXO 5 and MXO 5C oscilloscopes. It supports voltage and current measurements in a wide range of three-phase AC system configurations, providing engineers with a flexible solution for testing industrial automation equipment, power converters, motor drives and inverter applications.

A guided configuration wizard simplifies setup by assigning oscilloscope channels to the appropriate voltage and current probes while verifying system wiring. The software supports common two-wire, three-wire and four-wire configurations, including 2V2A, 3V3A and 3VN3A, ensuring quick and accurate measurement setup.
Once configured, the software performs cycle-by-cycle power analysis, delivering key electrical parameters such as RMS voltage and current, active power, reactive power, total power and power factor. Users can also define input and output configurations to calculate three-phase system efficiency, making the solution suitable for evaluating the performance of power electronic systems during research and product development.
Beyond basic measurements, the R&S MXO-K333 provides advanced analysis tools including phasor diagrams, harmonic analysis and Total Harmonic Distortion (THD) measurements compliant with IEC 61000-3-2 and MIL-STD-1399 standards. These capabilities enable engineers to assess power quality, analyze harmonics and validate compliance with industry requirements.

One of the software’s key advantages is its ability to combine advanced power analysis with the MXO oscilloscope’s existing capabilities. Engineers can simultaneously utilize FFT, math functions, automated measurements, advanced triggering, measurement tracking, spectrum analysis, protocol decoding and zone triggering while performing three-phase power measurements. This integrated workflow enables faster root-cause analysis without switching between multiple instruments.
By keeping captured waveforms visible throughout the measurement process, engineers can directly correlate electrical events with power behavior in real time. This approach significantly improves troubleshooting efficiency during product development, helping engineering teams shorten debugging cycles and accelerate design validation.
With the introduction of the R&S MXO-K333, Rohde & Schwarz continues to strengthen its portfolio of advanced test and measurement solutions for the electronics, industrial automation and power electronics industries. The software is now available worldwide for compatible MXO series oscilloscopes, offering engineers a comprehensive solution for three-phase power analysis, waveform visualization and advanced electrical testing from a single instrument.
