An oscilloscope and a device under test (DUT) constitute a de-facto system. In it, the most overlooked element is the interface between the two: the oscilloscope’s probes. Test personnel simply grab ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

The cable’s capacitance adds to the scope’s input capacitance and shunts the scope’s 1-M? input resistance, resulting in a time constant of approximately 100 µs. Such a severe low-pass filter begins ...

Capacitive displacement sensors turn tiny gaps into actionable signals. By measuring changes in capacitance as target moves, these devices deliver precise, non-contact readings of position and motion.
