hello all:
When test the ripple of the power of a board ,It's said that I should test it
below 20MHz.But I found that it's much defferent when I test the ripple in the
full band width frequency.As I think we should test the ripple without any
frequency limit ,or we can't observe the noise produced by other devices which
can couple into the power system .I hope someone will give me some
!advice,thanks
