Electromagnetic compatibility issues can sneak into your design in the unexpected ways - and your cables may be radiating more noise than the circuit itself. The distinction between common mode and differential mode noise is critical for identifying potential sources of radiated emissions. In this video we'll explore why these two modes behave differently when it comes to radiated emissions, and identify which one may cause the bigger problems. *Links:* ▸TekBox TBOH01 LISN: https://baltic-lab.com/LNK/TBOH01_LISN ▸TekBox LISN Mate: https://baltic-lab.com/LNK/LISN_MATE ▸TekBox TBCG4 Comb Generator: https://baltic-lab.com/LNK/TBCG4 ▸TBPS01 EMC Near-field Probes: https://baltic-lab.com/LNK/TBPS01 ▸TekBox EMCview: https://baltic-lab.com/LNK/EMCVIEW ▸Siglent SSA3021X: https://baltic-lab.com/LNK/SSA3021X ▸Tekbox TBMA1B Biconical Antenna: https://baltic-lab.com/LNK/TBMA1B *Support My Work:* ▸PayPal: https://paypal.me/BalticLab ▸Join this channel to get access to perks: https://www.youtube.com/c/BalticLab/join ▸Amazon Wishlist: https://www.amazon.de/hz/wishlist/ls/30L0WL27I7DJY ▸Visit my Blog: https://baltic-lab.com *German Content* ▸https://www.youtube.com/@balticlabor ▸Text Blog: https://baltic-labor.de *Social Media:* ▸https://www.instagram.com/balticlabde/ 0:00 Intro 0:28 Differential Mode 3:14 Common Mode 4:38 Improved Measurement 5:24 Far Field Measurement 7:12 Announcement #electronics #electricalengineering #diy
