Description

Rohde & Schwarz NPA701 Power Analyser & Compliance Tester

In harmonic analysis, the R&S®NPA701 power analyser graphically displays up to the 50th harmonic in a logarithmic amplitude scale. The user‑configurable, dual‑channel trend chart function for U, I, P, S, Q and F is unique in this class of instruments. The brilliant QVGA colour display (320 × 240 pixels) simultaneously displays up to 10 user‑configurable measurement results with a refresh rate of 10 measurements per second. The instrument has a basic accuracy of 0.05%. Signals are acquired from DC to 100 kHz at a sampling rate of 500 ksample/s. Current and voltage are displayed with 16-bit resolution. The logging function lets users store measured data with a timestamp in CSV format for a nearly unlimited period of time. Screen content can also be saved to a USB flash drive anytime at the push of a button. A PASS/FAIL function lets users monitor numerous measurement results.

The instrument has wizards for the IEC62301 (standby), EN50564 (extended standby) and EN61000-3-2 (harmonic current for EMC, CE approval) standards, enabling autonomous measurements without a PC.

Applications

Pre-Compliance Testing: Verifying products meet international energy standards before official lab certification.
Quality Assurance: Standardised, repeatable testing of consumer electronics for global markets.
EMC Verification: Checking current harmonics to ensure CE approval compliance.

Product Images

All tests conducted with our compliance testers adhere strictly to the following standards:<br />
<br />
<ul><li>IEC62301: standby power consumption</li><br />
<li>EN50564: standby power consumption</li><br />
<li>EN61000-3-2: harmonic currents for EMC, CE approval</li></ul><br />
<br />
<br />
<br />
A user-friendly step-by-step wizard helps throughout the measurement process by automatically configuring the necessary instrument parameters. This approach minimizes potential measurement errors and ensures quick access to results. No prior familiarity with the aforementioned standards is required. Upon completion of testing, the system generates verification reports, eliminating the need for an external PC

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.

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 time base, 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

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.

Inrush Measurement Learn more...

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 analyser . An automatic hardware trigger initiates each acquisition and the waveform is continuously refreshed. Alongside waveform visualisation, the R&S®NPA furnishes numerical outputs for RMS voltage, RMS current and power, with softkeys for selecting displayed or concealed traces

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.
