the compact class, that has it all
The R&S®NPA series of single phase power analyzers comprises a comprehensive range of compact testers meticulously designed for AC/DC load or standby current characterization, boasting a fundamental accuracy of 0.05% and low current measurement capability down to 5 milliamps. Setting itself apart from competitors in 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 facilitates the comparison between the switching on and the steady-state operation of the device. The system enables continuous recording of 8192 samples, accommodating recording durations spanning from 16 milliseconds to 67 seconds. Following a trigger event, akin to executing a single-shot capture on an oscilloscope, voltage and/or current are graphically plotted.

Graphical display versus time
This graphical mode facilitates the plotting of up to two measured variables against time, similar to the roll mode feature found in oscilloscopes. Primarily employed for observing more extended timeframes, it accommodates data ranging from 40 seconds to 80 minutes on the display. Users can decide the variables for plotting and adjust the timebase, while the vertical trace scaling is managed automatically. During operation, the numerical representation of maximum and minimum values is provided on the screen for enhanced analysis
Simultaneous display of voltage and current versus time
Oscillographic waveform chart
This function facilitates a graphical representation of voltage, current, and/or power across a single waveform period, akin to the display format on an oscilloscope. The period is automatically determined by the power analyzer R&S®NPA. 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 enabling the selection of 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 computation of Root Mean Square (RMS) values and phase angles for harmonics. The accompanying bar chart elegantly visualizes patterns for up to 50 harmonics of voltage and/or current, while the tabular presentation offers comprehensive insights into magnitude and phase values per harmonic. Additionally, users have the flexibility to selectively display odd or even harmonics. The intuitive interface allows seamless navigation through the data, with cursors or a rotary knob enabling users to focus on individual harmonics, highlighted in a distinctive yellow hue.

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