For
pulsed CV measurement,
The
whole figure of input voltage is shown below, since the pulsed measurement is
very fast, each pulse lasts for about 200us
,
it is not clear to display results in one graph, so the results will be shown
in segmentations.

For
the first segment, the input voltage and output voltage are plotted below:

In pulsed CV
measurement, the output voltage is proportional to capacitance of the sample
(the load resistor is relatively small). The above figure generally displays
the shape of a CV plot. A detailed calculation for capacitance can be found here:
