The Italian manufacturer AFJ Instruments has a widely applicable and competitively priced range of LISNs (line impedance stabilization network). They are intended for line-bound interference measurements in accordance with CISPR 16-1-2 in both AC and DC power supply networks.

The use of air coils in the current path prevents saturation effects 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 single and three phase versions where switched measurements are allowed according to CISPR 14-1.

In addition to LISNs, AFJ Instruments also has FTT based EMC receivers, Click analysers, Van Veen Loop antennas, Van Der Hoofden test head and measuring transducers in accordance with the international CISPR 16 standard.
