And I was wondering if you lot have any tips or suggestions as to how I can use it to measure ripple current. I mainly want to use it to check the output of PSUs, both unloaded and under load, and see if the ripple is bad.
I know that most PSUs do have a small amount of ripple, but how much is too much? So far I've measured a PC laptop PSU, and an Apple iBook PSU, both of which have some ripple. The PC laptop PSU seems to be a constant amount of ripple, but the iBook PSU has the ripple changing randomly! There also seems to be some interference creeping along the line on the scope when I measure that PSU - perhaps the PSU is going bad?
