Hello All,

I have been asked by one of our design engineers if I can measure the RF
signature on the 3v plane on one of our PCB designs. The purpose of this is
to compare it to proposed changes for cost reduction, ie removal of bypass
caps. I would assume I need some sort of CDN but I have no designs for this
application. Does anyone have any ideas on how I can safely probe a 3v DC
power rail with an EMC analyser (HP8591E)?
