Description

The R&S® NPA501 power analyzer 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.

Moreover, the R&S® NPA501 power analyzer offers peak value measurements, the graphical display of measured values and the analysis of up to 50 harmonics. The dual‑channel trend chart function, which is unique in this instrument class, can be freely configured from 15 measurands. The inrush function captures and graphically displays inrush current and voltage waveforms. The PASS/FAIL function lets users monitor numerous measurands on the screen and externally via an analog and digital output on the rear panel. An additional sensor input for a current probe or shunt expands the instrument's current measurement range as required.

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.

The R&S® NPA501‑G additionally have an IEEE‑488 interface (GPIB).
