2.4 EMI

Conducted emissions measurements were taken using both quasi-peak and average 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 this test, a resistive load was used to apply a 1.98-W load to the output.
