Abstract

A broad-band digital harmonic vector voltmeter previously proposed and theoretically studied by the authors was implemented by using a special-purpose random sampling strategy to avoid the bandwidth limitations due to the finite conversion time of the S/H-ADC devices. The experimental results showed that the bandwidth of the instrument is limited only by that of the S/H devices of the acquisition channels, according to the theoretical findings. The maximum amplitude error was not greater than 2%
