Line Impedance Stabilization Network
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A line impedance stabilization network (LISN) is a device inserted between the power mains and an equipment under test to provide a stable impedance at radio frequencies. It also isolates the test setup from the mains and allows measurement of conducted emissions.
Example in context
“Conducted emission measurements were taken using a LISN placed between the power supply and the device under test.”
“Güç kaynağı ile test edilen cihaz arasına yerleştirilen bir LISN kullanılarak iletim emisyon ölçümleri yapıldı.”
Where engineers use it
The LISN is a standard fixture in EMC conducted emissions testing per CISPR 16. Engineers must use it to create a defined impedance environment and to couple measurement receivers to the power lines.
Synonyms: LISN, artificial mains network, AMN
Practice: can you use “Line Impedance Stabilization Network” at work?
During a pre-compliance test, the engineer observes inconsistent conducted emission readings. They suspect the LISN grounding is faulty. What steps should be taken to verify the LISN integrity?
Show a model answer
“Ensure that the conducted emission measurement setup includes a properly calibrated LISN.”
