The R&S®NPA family of power analyzers are a comprehensive package of compact measuring instruments for the characterization of AC/DC load or quiescent current with a basic accuracy of 0.05%. The devices enable power measurements over a wide range from 50 µW to 12 kW, and enable signal acquisition from DC to 100 kHz at an impressive sampling rate of 500 kSamples/s. In addition to the numerical display of 26 critical parameters, the devices offer optional graphical functions and conformity protocols aligned with industry standards, depending on the model. The R&S®NPA101 power meter provides basic measurements in the areas of voltage, current, power and distortion. For further analysis, the P&S®NPA501 power analyzer offers peak-peak measurements, four BNC connections for analog and digital inputs and outputs, graphical functions such as waveform and trend diagrams, inrush function, harmonic recording and a PASS/fail function, Ideal for production tests. An additional sensor input for conn
