Using LabVIEW to Record and Measure the RMS Voltage Of a Distorted Waveform

This paper presents a measuring stand designed to record and measure distorted signals. The study used selected measuring instruments and a PC with an application written in the LabVIEW environment. The developed programme algorithm includes SCPI commands for instrument configuration, signal generation and remote measurements. Communication with the instruments was realised via USB and LAN. The performed computer measuring stand makes it possible to record the waveform and its generation and to compare the results of measuring the RMS value of the distorted voltage with different instruments.
