So I'm trying to do some regulator PSRR tests and for this i'll need a regular DC source with a ripple on it (say 200mv pk-pk) so i can compare this to the ripple at the output and someone suggested this circuit set up to me. My question is about the capacitor, i was told "a signal generator might not be able to handle DC on its output so a capacitor may be needed".First of all I'm not sure if this is true and second of all I'm not sure what it means or how a capacitor would solve this problem,and if it does how to figure out the capacitance to use.
