The Rohde & Schwarz NPA101 is part of the R&S NPA series of single-phase power analysers. It is designed for AC/DC load or standby current characterisation with an accuracy of 0.05% and a low current measurement of 5mA. In comparison to the other NPA models, this product only has the basic measurement functions and requires additional tools for graphical analysis and compliance testing.
It has numerical displays with a fast update rate of 100ms and an auto-range function to enhance testing efficiency. Furthermore, the product features frequency and adaptive filters to eliminate unnecessary noise, ensuring smooth and accurate results. The display content can be saved to a USB flash drive or shared through the LAN and USB interfaces.
Unique to this series is the timestamped logging to CSV for a nearly unlimited period. However, if further enhanced measurement functions and graphics are required, the R&S NPA501 is recommended. And if the evaluation functions have to be in line with IEC 62301, EN 50564 and EN 61000-3-2 industry standards, the R&S NPA701 is recommended. For the full range of available functions (per model), please see the table in the images.
