Get more visibility into your power systems with Advanced Power Measurement and Analysis on the 5/6 Series MSO. The combination of the oscilloscope, analysis software, and a wide range of available voltage and current probes, enables you to perform automated, accurate power system measurements even if you are not a power conversion guru. The 12-bit analog-to-digital converters in the 5/6 Series MSO deliver high-precision measurement data, and the pinch/swipe/zoom touch interface makes it easy to manage measurements. A rich set of graphical power analysis tools, signal visibility on up to 8 (5 Series MSO) and 4 (6 Series MSO) FlexChannel® inputs, and a 15.6-inch HD display, deliver a comprehensive view of your power system. The instruments support a wide range of voltage and current probes, including state-of-the-art IsoVuTM optically isolated voltage probes. The unmatched common mode rejection of IsoVu probes and the automation of Advanced Power Measurement and Analysis make an unbeatable combination for optimizing the latest GaN and SiC designs.

Input analysis

Power quality measurements, Current Harmonics, Input Capacitance, and Inrush Current are the four common sets of measurements made on the input section of a power supply, to analyze the effects of the power supply on the power line and evaluate the performance of the supply under various line conditions.

Power Quality

These measurements are optimized for line frequencies and are commonly performed at the AC line input of the power supply. They provide fast insight into the amount of power and the level of distortion at the input.

Measurements include:

  • RMS voltage and current

  • Frequency

  • True, apparent, and reactive power

  • Power factor

  • THD and crest factor
