EMI

The following conducted emissions measurements were taken using both quasi-peak detector and average-peak detector methods (yellow and green traces, respectively). The measurements are compared to the CISPR-25 Class B regulations for quasi-peak and average tests. For these tests both the outputs were loaded to full output loading with resistive loads.
