Total EMI
The total EMI is a combination of both Common mode and differential mode noise.
When looking at the complete noise spectrum it is sometimes difficult to identify the individual noise sources.
With the EMIfix network it is easy just to press the CM or DIFF button to identify whether the noise is Common mode noise or Differential noise.
Start solving the problems related to the Differential mode noise and go back to the L or N settings to find out how much the total EMI spectrum has been reduced.
