Hi Doug:
While I don’t yet have the answer (and may never have the answer), I ran across this quote from Luigi Galvani which I think applies here: “For it is easy in experimentation to be deceived, and to think one has seen and discovered what we desire to see and discover.” Best regards, Rich From: Doug Smith [mailto:[email protected]] Sent: Friday, January 26, 2018 2:50 PM To: [email protected] Subject: [PSES] Measurement dilema Hi All, Can you explain the result in this video I just made? Scope plots of the same two nodes are completely different. Probes and scope are operating normally, no problem with the equipment itself. If you have been to my seminars you know the answer, please do not post the answer unless you have not seen this experiment until now. Hint 1: There are no EM fields radiating from the shielded box affecting the probes. Hint 2: There are no active components inside the box. https://youtu.be/qj-HBFMEJiY Doug <https://hostingemail.xo.com/api/storage/[email protected]/signatures/images/2476c205-f457-4395-87cc-7aa199c734f2> - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
