The R&S NPA101 power meter offers basic measurements of voltage, current, power, and total harmonic distortion (THD). The 5 V measurement range provides a previously unattainable level of resolution for power and energy measurements.

The power meters of the R&S NPA family set standards in the documentation of measurement parameters: they simultaneously display up to 10 user-configurable measurands with a refresh rate of 10 measurements per second. A logging function lets users store this data with a timestamp in CSV format for a nearly unlimited period of time. In addition, screen content can be saved to a USB flash drive anytime at the push of a button.

The instrument's standard hardware‑based integrator delivers highly precise, seamless power consumption analysis and adds up watt and ampere hours according to polarity.

Three different filters in the voltage and current circuit of the acquisition system can be activated for the measurement task.

All instruments of the R&S NPA family can be remotely controlled via the Ethernet or USB interface. The virtual COM port and the test and measurement class (TMC) are supported for communications via USB. The remote-control commands are completely based on the SCPI standard. Cost-free driver packages for LabVIEW, LabWindows/CVI and IVI.net are also available. They allow the R&S NPA instruments to be integrated quickly and easily into existing systems.
