Hello min. Your videos are rally very helpful. We are testing high power three phase ac equipments which has high voltage switching . We put some standard emi filters at the input of the LIsN to minimise the ambient noise. It seems to work. But do you think this is a good idea or can you suggest some alternative.
Hi Min, thx for this video! It solves some problems which I encountered. But also raises some questions 😅: 1) instead of using the powercables with ferrites. Could we also use a coax/shielded cable? Maybe coax is not a good example because the gnd is not the shield. 2) same for the connection between the DUT/LISN. At the time you connected them the span was bigger. Could we also suspect noise from the environment coupling into the wire? I think usually the original powercord is used of the DUT? (If applicable) 3) I see ground is connected between the two LISN’s and I guess also the electronic load. If the DUT has a earth/gnd, also connect that one? 4) LISN is put in dBuV mode. Current probe in dBa. Should we also put H-field probes in dBa and E-field probes in dBuV?
