Oscilloscope Probe Capacitance
Low capacitance probes are a type of passive, analog voltage probe, alongside high voltage and general-purpose probes. The most basic probe, a passive probe, is also the most versatile. When used with select attachments, passive probes can be used with higher-speed signals. Additionally, Yokogawa Test&Measurement provides probes for extreme cases including high-voltage, wide temperature ranges, and high-speed signal measurement.
Measuring Capacitance with an Oscilloscope
How to measure capacitance with an oscilloscope: Measure the time of charging to a given voltage using a simple circuit for a capacitor in series with a resistor. Then, the oscilloscope helps to measure the voltage across the capacitor.
