Capacitance is the measured value of the ability of a capacitor to store an electric charge. This capacitance value also depends on the dielectric constant of the dielectric material used to separate the two parallel plates. …
If the frequency is too low, the capacitor finishes charging too early, and if it is too high, the capacitor will not charge all the way. When you have the waveforms as they should be, adjust the DSO''s horizontal controls to spread out the signal and allow more of the x-axis to be used for time calculation.
