Rohde & Schwarz Unveils New R&S NPA Family of Compact Power Analyzers

fifth April 2024: A brand new household of Rohde & Schwarz energy analyzers is now out there in three fashions to satisfy all necessities for measuring voltage, present, energy and whole harmonic distortion on each DC and AC sources. The R&S NPA101 energy meter gives all primary measurements, the R&S NPA501 energy analyzer provides enhanced measurement capabilities and graphical evaluation, and the R&S NPA701 compliance tester contains analysis capabilities consistent with IEC 62301 and EN 50564 for energy consumption and EN 61000-3-2 for EMC harmonic emission testing.

The new R&S NPA household of energy analyzers is now out there in three fashions.

The electrical traits of a tool or module are a elementary property that’s measured all through the electronics business, beginning with the event, throughout compliance testing, all through manufacturing and through service. All fashions of the brand new R&S NPA household of energy analyzers meet the necessities in any respect of these levels for energy measurements at ranges from 50 µW to 12 kW, at potential variations from 1 mV to 600 V and currents from 1 mA to twenty A. The R&S NPA501 and R&S NPA701 embrace interfaces for exterior probes or shunts to increase the vary even additional. All three fashions characteristic a excessive sampling price of 500 ksample/s to detect even the shortest transient ripples in output. The 16-bit decision A/D convertor ensures an accuracy of ± 0.05 % for each present and voltage readings.

The three devices of the R&S NPA household embrace the identical 23 commonplace measurements of energy,
present, voltage, harmonic distortion and power. Users can choose as much as ten measurements to be displayed from a complete of 37 to show concurrently on the display with a refresh price of 100 ms. The display contents may be output as a graphic to the USB port, the values may be recorded over time for all measurements with the logging operate. The 5V measurement vary gives best-in-class decision for each energy and power measurements. A alternative of Crest issue values of 1, 3 or 6 gives best-in-class flexibility to seize all peaks and maximize dynamic vary.

All devices of the household incorporate a LAN and USB interface for distant management; the R&S NPA501-G and R&S NPA701-G fashions even have a GPIB interface. An entire set of SCPI instructions in addition to
drivers for LabVIEW, LabWindows/CVI and IVI.internet can be found for simple integration of the devices into programs. Users profit from the compact type and footprint; for system use, two devices may be
mounted side-by-side in a 19” rack.

In addition, all R&S NPA501 and R&S NPA701 fashions have most and minimal peak values for
1/2 voltage, present and energy. With the PASS/FAIL operate, customers can outline as much as six units of most and minimal values to verify simply whether or not the DUT’s output stays inside the limits. Both devices additionally characteristic a graphical show mode. In the time area, customers can view the power-up inrush attribute, the voltage and present waveforms concurrently, or a variety of parameters over longer intervals. In the frequency area, customers can view as much as the fiftieth harmonic, logarithmically if required or as a desk.

The prime mannequin of the household, the R&S NPA701 compliance tester, moreover gives step-by-step
procedures consistent with IEC 62301 and EN 50564 for energy consumption in low-power modes, and EN
61000-3-2 for EMC harmonic emissions. Users who will not be accustomed to the official commonplace procedures may be assured that they’re performing compliance checks appropriately and that the outcomes are legitimate. The R&S NPA701 is the one energy analyzer in its class that doesn’t require a separate PC to carry out compliance checks.

The R&S NPA household of energy analyzers replaces the R&S HMC8015 energy analyzers, each as a drop-in
alternative and to make use of collectively as required. The devices are half of the R&S Essentials portfolio,
out there from Rohde & Schwarz and chosen distribution channel companions.

Rohde & Schwarz will reveal the brand new R&S NPA household of energy analyzers at embedded world
Exhibition in Nuremberg at sales space 4-218 in corridor 4.
