So - in the case of a linear power supply - the rectified output of
the transformer typically goes straight to a big old storage cap for
smoothing purposes. My question is: how much ripple should I expect to
see across that cap if all's working well? I have to say I'm seeing a
*lot* of ripple on this cap in a Marconi RF signal generator and it's
finding its way to the RF output, which of course should ideally have
zero ripple on it. The aforementioned cap tests fine WRT ESR and
capacitance in-circuit, I should add.
Thanks,
