Hi all, i am trying to measure noise on a PCB directly across a decoupling capacitor. The PCB has buried/ blind vias and has no specific power noise test points. My question is, will there be a difference in the measured noise if i measure noise across the capacitor and if i remove the capacitor and probe at the pads? I cannot remove the capacitor to do a what-if as i have only one board. thanks in advance, Virendra Adsure --------------------------------- Do you Yahoo!? The New Yahoo! Search - Faster. Easier.
