the compact class, that has it all
The R&S®NPA series of single phase power analyzers is a comprehensive range of compact testers meticulously designed for AC/DC load or standby current characterization with fundamental accuracy of 0.05% and low current measurement down to 5 milliamps. Unlike other competitors on the market, these analyzers:
Evaluation functions according to IEC 62301, EN 50564, or EN 61000-3-2
All tests conducted with our compliance testers adhere strictly to the following standards:
Typical test setup with R&S®NPA-Z1 socket adapter
Graphical view over one waveform period
Utilize a graphical representation to depict occurrences such as fast switch-on operation. This approach simplifies comprehension and helps compare the switching on and the steady-state operations of a device. The system can continuously record 8192 samples with durations of 16 milliseconds to 67 seconds. After a trigger event (similar to a single-shot capture on an oscilloscope), voltage and/or current are graphically plotted.

Graphical display versus time
This graphical mode can plot up to two measured variables against time, similar to the roll mode in oscilloscopes. Primarily used observing longer time periods, it can accommodate 40 seconds to 80 minutes of data on the display. Decide on the plotting variables and adjust the timebase, while the vertical trace scaling is done automatically. When operating, the numerical representations of maximum and minimum values are visible on the screen for enhanced analysis
Simultaneous display of voltage and current versus time
Oscillograph waveform chart
This function helps create a graphical representation of voltage, current, and/or power across a single waveform period, similar to the display format on an oscilloscope. The period is automatically determined by the R&S®NPA power analyzer . An automatic hardware trigger initiates each acquisition and the waveform is continuously refreshed. Alongside waveform visualization, the R&S®NPA furnishes numerical outputs for RMS voltage, RMS current and power, with softkeys for selecting displayed or concealed traces
Simultaneous display of voltage, current and power for one period
Harmonics as bar chart or table view
Harmonic mode enables the computing of root mean square (RMS) values and phase angles for harmonics. The accompanying bar chart elegantly visualizes patterns for up to 50 voltage and/or current harmonics, while the tabular presentation has comprehensive insights into magnitude and phase values per harmonic. Users can also selectively display odd or even harmonics. The intuitive interface allows seamless navigation through the data, with cursors or a rotary knob so that users can focus on individual harmonics, highlighted in a distinctive yellow.

Real-time integrator
The integrator function serves a special purpose in unstable power measurements. The function is designed to compute and present the cumulative DUT power or energy consumption across a designated time span in both the active and standby states. Users can flexibly select their preferred acquisition mode, choosing between manual, time-based or event-based options. All R&S®NPA models deliver results in various formats, including positive, negative, and total watt-hours, with continuous updates in real time.
