LISNs Explained in Simple Terms: What Is the Job of a LISN & Why Do We Need it for EMC Testing

A LISN (Line Impedance Stabilisation Network) is by far simpler than its complicated name suggests. In this video, Dr Ali Shirsavar from Biricha Digital explains the purpose of using a LISN, its functions, its circuit and why we have to use one when doing EMC measurements.
In the next video we are going to dissect a LISN and see what is inside

I am lucky that i came across this explanation. Many thanks!

[@TheHareidGamer]

Thank you, clear and good explanation!
One thing I would like to note for people developing products that will be tested with a LISN, is that if you are unlucky your EMI RC snubber circuit can actually start oscillating when connected to a LISN due to the added inductance of the LISN. Have seen it several times in DC luminaries!

Wow, thank you. That is the best and most understood explanation I have come across. 🙂

[@hadihachem8885]

Excellent video and explanations!

I see the new Bode 100 in black sandwiched between the ones in blue!

Is there a BOM for building your own mains connected LISN?
Building or buying a good 50uH inductance is the tricky part I suspect.

Hi, would you be able to comment on if the circuit elements to make a LISN are simple, why are professional LISNs used in EMC testing expensive?

[@federicomodina]

Hi Dr. Shirsavar, thank you for your explanation. Is It possibile use a LISN to inject noise to the DUT, connecting a signal generator to the port?

[@federicomodina]

@@para-gz5bn Thanks for the reply. I should look into this further.

[@tingdongyan7502]

Great explanation, Dr. Do you know How these component values are decided?
