EMI filtering and conducted EMI pre-compliance measurements

AN3065

Doc ID 16279 Rev 2

As visible in the diagrams, in all test conditions there is a good margin of the measures with

respect to the limits. The measurements have been done in peak detection to speed up the

sweep, otherwise taking a long time. Please note that the measurements done in quasi-

peak or average as required by the regulation will be much lower because of the jittering

effect of the TM control that cannot be evaluated in peak detection.
