waveform ringing frequencies in the power supply.
7) Examine entire frequency range for balanced or unbalanced
common mode components close to or in excess of the
specification limit. Make measurements on both Line and
Neutral LISN. Pay special attention to frequency ranges around
measured component resonances and identified circuit ringing
frequencies. Use average or quasi-peak detection as required to
properly compare measured reading with limits of the chosen
standard. Modify common mode filter design if necessary.
8) Remove splitters. Measure signals from both Line and
Neutral over the entire frequency range. Emissions above 1
Mhz are usually common mode. Solve spatial coupling effects
using additional Y-capacitors (see Figures 41 and 42), improved
transformer construction (see Figures 35 and 36), higher
bandwidth two section common mode choke (see Figure 21),
additional high frequency common mode choke (see Figure 27)
or shielding techniques (Figures 44-46).
9) Perform final test with secondary connected to ground and
also with secondary isolated from LISN ground.
