I'm trying to determine the capacitance of a sensor, but the oscilloscope's internal capacitance is loading the measurement too much.
What is an appropriate method to determine a low picofarad capacitance using an o'scope in this situation? (o'scope internal capacitance is 24pF).
Make a measurement of 'nothing', that is your scope's input capacitance. Then make a measurement of the 'sensor', that is your scope's input capacitance + the sensor's capacitance. Subtract.
