Thanks so much for your good video about EMC test
Thanks!
As always a great video from Paul Denisowski, great job.
Thanks! Appreciate the feedback! :)
Good video. LISN'S aren't just for mains AC of course.
@@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!
@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.
@@robertbox5399 (laughs) That's a great example - thanks for sharing!
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
Great job 👏
Thank you!
