UCD3138 PFC tuning

Hi,

on setting up the tuning for the PFC current loop of UCD 3138, is there any specific setting (other than specified in SLUA709)  involved for  using the Venable-3120 Analyzer.  During my tuning analysis using an AP300, I find an additional 120HZ noise being picked up by the loop. Can I know the possible source of this noise signal from the UCD3138EVM setup if any.

Thanks.
