Single-ended capacitance probes or ‘push/pull’ capacitance sensors can be used for this specific application to monitor the distance between probe and rotor while spinning. When a push/pull sensor is ...

The capacitive loading of a probe tip has another effect beyondloading of the DUT. A single-ended probe requires a ground connection.This ground lead has inductance associated with its length.

Capacitance probes detect the presence or absence of material in contact with the probe by sensing very small changes (as low as 0.5 pF) ...

Thus more-than-typical interest in inline capacitance probes, which distinguish living cells from “everything else” by the capacitance changes objects induce in the probe as they interact with it.

From guest blogger Gregory Davis: Selecting the right probe is an all-important choice when it comes to acquiring a signal. As we discussed in my last post, not all probes are created equal. Many ...

Instead, the input capacitance is the sum of the cable capacitance and the scope’s input capacitance—for example, the Tektronix P6101B 1:1 2-m probe has a 15-MHz bandwidth and 100-pF input C.
