Voltage Probes
In addition to EMI measurement with LISNs (Line Impedance Stabilisation Networks, Artificial Mains Networks), Probes are used for Terminal or Line voltage measurement.
LISNs are required to feed the Equipment under Test (EuT) with mains power, to reduce external line interference, to offer the EuT a standardized impedance and to route the extracted r.-f. voltage to the EMI receiver.
