LISN - Line Impedance Stabilization Network
A helper circuit for EMC/EMI precompliance testing
The assembled prototype
✈ Motivation
Reducing the noise of a power supply was the task the student wanted to achieve.
On the other hand, some Hameg 5012 were looking for a new job. This inspired me to
go for a EMI-Precompliance Test-Setup.
As commercial solutions have astronomical price-tags, we went the diy way. And yes,
approx. 20 dB cheaper :-)
✈ The Design
The design is similiar to others out there. Depending on the norm, you may want to
assemble 10 x 1 µH or 10 x 10 µH or whatever deems suiteable for you.
The first Prototype was assembled with 10 x 680 µH and that resulted in the S21
measurement below :
