Re: Some more on Jeff's never ending saga to tackle home grown EMI

Hi Arie,
?
very good point.
?
Indeed I have built also a limiter circuit with a BNC jack and a plug. I simply plug this onto the BNC port of the LISN to protect the test equipment.
?
I guess I should add that information eventually to my description.
?
Kind regards

Hi Matthias,
A nice design and well build.
I have used equipment like this professionally and one item that I added are clamping circuits over the output to the spectrum analyzer.
The input of that expensive equipment often cannot withstand the switching spikes when the LISN's output load is switched on or off.
Just check it with a scope, the transient on that BNC output can be very high.

Arie de Muijnck

I have built something similar also based on Thilo¡¯s inputs and it is very helpful:

Sorry it is only in German but I am sure the pics and sketches together with an online translator should help to understand
