Abstract
For fast measurement of radio-frequency interference voltages (also called RFI voltages) within a predetermined frequency range in conformity with rating standards, the maximum and minimum peak voltage levels are measured during tuning of the frequency range; when the maximum peak voltage level exceeds a predetermined limit value,the tuning process is interrupted and a quasi-peak measurement is performed at this instantaneous frequency.
