Investigation & EMC tuning

Goals

The objectives of the training Investigation & EMC tuning :

Upon completion of this training course, participants will be familiar with the investigative methods associated with specific tests in order to identify problems and to be able to design and implement appropriate protective measures.

The purpose of this training is to:
• Define the objectives required to comply with EMC testing
• Analyze and identify non-conformities in EMC testing
• Be able to adapt investigative methods based on the issues encountered
• Master EMC solutions and their implementation
• Be able to implement your own diagnostic tools

Session dates:
• from 28/09/2027 to 30/09/2027 - Trappes
