It is possible to get noise induced on all cabling at the same time. In this case it will be also be present on the ground lead. To reduce this noise "ground chokes" are used. It is also extra attenuation for common mode currents.

Subject: Doubt on LISN utilization
Hello All,
I have a LISN from EMCO and it has a "Ground Choke". What's the goal of
this Ground Choke? Is it really needed in the conducted measurements?
Could somebody make this clear to me?
Thanks in advance
Muriel
