Hi all.
I'm preparing for a lab regarding frequency response/stray reactances and the like in oscilloscope probes. If you look at the attached picture, this is the equivalent model they've given for us to consider.
One of the questions asks, "What is the effective input resistance and input capacitance for the probe?"
I'm really not sure how to go about answering that. It doesn't specify for any particular frequency so I don't think it will involve working out the impedance of C1 and C2. Oh by the way it asked you to work out C1 before using this relationship:
9*C1 = (C2 + C3) so I would say C1 is around 11pF.
Any help please?
Cheers.
