Thanks so much for your good video about EMC test

[@pauldenisowski]

Thanks!

[@jesus_pimienta]

As always a great video from Paul Denisowski, great job.

[@pauldenisowski]

Thanks! Appreciate the feedback! :)

Good video. LISN'S aren't just for mains AC of course.

[@pauldenisowski]

@@robertbox5399 Of course :) In my experience, the vast majority of LISNs used in precompliance are AC mains connected, so that's why I focused on those in this presentation. Thanks for the feedback!

[@robertbox5399]

​@pauldenisowski We asked a local university if it had a LISN for automotive testing. They said yes and then showed me a pic of a box with a mains socket on it! Will be sharing this video to some management with a software background who think EMC is witchcraft Lol.

[@pauldenisowski]

@@robertbox5399 (laughs) That's a great example - thanks for sharing!

[@EdriesMohsen]

Great job 👏

[@pauldenisowski]

Thank you!

Plz upload a video how to add instruments in EMC software and how to make test setup for Power disturbance according to CISPR 14-1
