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 ...

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 ...

Viable cell count (VCC), a critical parameter in both microbial and mammalian cell cultures, fluctuates during batch and fed-batch cultures. VCC is determined conventionally through sampling and ...

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.

An important design objective for voltage and current probes and current monitors is to determine a signal’s characteristics without significantly affecting the signal itself. In other words, the ...

Over the past decade, demand for nano-electrical characterization has rapidly increased due to the continuous miniaturization of electronic devices. The semiconductor and microelectronics industries ...
