Elektor Dual DC LISN (150 kHz - 200 MHz)

Measuring conducted emission is the simplest and most affordable method of getting some indication of whether a design can meet EMI/EMC requirements. A Line Impedance Stabilization Network (LISN) is an indispensable part of an EMC pre-compliance test setup.

In cooperation with Würth Elektronik, Elektor has developed a 5 µH, 50 Ω Dual DC LISN that supports voltages up to 60 V and currents up to 10 A.

The instrument measures RF interferences on both channels (the power supply) by means of 5-μH blocking inductances. The internal 10-dB attenuation network – one in each channel – contains a 3rd-order high-pass filter with a cutoff frequency of 9 kHz to protect the input of instruments like a spectrum analyzer from potentially harmful DC voltages or low frequencies coming from the EUT (Equipment Under Test).
