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 complete harmonic distortion on each DC and AC sources. The R&S NPA101 energy meter supplies all primary measurements, the R&S NPA501 energy analyzer provides enhanced measurement features and graphical evaluation, and the R&S NPA701 compliance tester contains analysis features according to IEC 62301 and EN 50564 for energy consumption and EN 61000-3-2 for EMC harmonic emission testing.

{The electrical} traits of a tool or module are a elementary property that’s measured all through the electronics trade, 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 those 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 embody interfaces for exterior probes or shunts to increase the vary even additional. All three fashions characteristic a excessive sampling fee 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 embody the identical 23 normal measurements of energy, present, voltage, harmonic distortion and vitality. Customers can choose as much as ten measurements to be displayed from a complete of 37 to show concurrently on the display with a refresh fee 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 perform. The 5V measurement vary supplies best-in-class decision for each energy and vitality measurements. A selection of Crest issue values of 1, 3 or 6 supplies 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 straightforward integration of the devices into programs. Customers profit from the compact kind and footprint; for system use, two devices may be mounted side-by-side in a 19” rack.

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

The highest mannequin of the household, the R&S NPA701 compliance tester, moreover supplies step-by-step procedures according to IEC 62301 and EN 50564 for energy consumption in low-power modes, and EN 61000-3-2 for EMC harmonic emissions. Customers who will not be conversant in the official normal procedures may be assured that they’re performing compliance exams accurately 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 exams.

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

Rohde & Schwarz will show the brand new R&S NPA household of energy analyzers at embedded world Exhibition in Nuremberg at sales space 4-218 in corridor 4. For extra info on the R&S NPA household of energy analyzers go to: www.rohde-schwarz.com/product/NPA
