Rohde & Schwarz introduces new NPA family of compact power analyzers for all power measurement requirements

A new family of Rohde & Schwarz power analyzers is now available in three models to meet all requirements for measuring voltage, current, power and total harmonic distortion on both DC and AC sources. The R&S NPA101 power meter provides all basic measurements, the R&S NPA501 power analyzer adds enhanced measurement functions and graphical analysis, and the R&S NPA701 compliance tester includes evaluation functions in line with IEC 62301 and EN 50564 for power consumption and EN 61000-3-2 for EMC harmonic emission testing.

The electrical characteristics of a device or module are a fundamental property that is measured throughout the electronics industry, starting with the development, during compliance testing, throughout production and during service. All models of the new R&S NPA family of power analyzers meet the requirements at all of these stages for power measurements at levels from 50 µW to 12 kW, at potential differences from 1 mV to 600 V and currents from 1 mA to 20 A. The R&S NPA501 and R&S NPA701 include interfaces for external probes or shunts to extend the range even further. All three models feature a high sampling rate of 500 ksample/s to detect even the shortest transient ripples in output. The 16-bit resolution A/D convertor ensures an accuracy of ± 0.05 % for both current and voltage readings (more info).
