The Italian manufacturer AFJ Instruments has a widely applicable and competitively priced range of LISNs (line impedance stabilization network). These are intended for measuring line-related interference measurements in both AC and DC power networks in accordance with CISPR 16-1-2.
By using air coils in the current flow path, saturation effects are prevented and the large wire cross-section of the coils guarantees a continuous high current load.
All AFJ Instruments LISNs have an artificial zero PE simulation network, built-in pulse limiter and a 10dB attenuator.
AFJ offers LISNs in both one- and three-phase versions where switched measurements are permitted according to CISPR 14-1.
In addition to LISNs, AFJ Instruments also has FTT based EMC receivers, Click analyzers, Van Veen Loop antennas, Van Der Hoofden test heads and measuring transducers in accordance with the international CISPR 16 standard.
