[IMSAI Guy] wants you to build a non-contact scope probe. The cost? Assuming you have a bit of wire and a regular scope probe, it won’t cost you anything. Why do you want such a thing? You can see ...

Oscilloscopes require probes to work, and probes are not all the same. There's a wide variety with versions designed for specific tasks and applications. This ...

Evaluation Engineering has a great article about scope probes from a guy at Agilent. Jae-Yong Chang gives a pretty good overview of the issues surrounding scope probes. I would add two stories of my ...

Probing solution is industry first to operate at bandwidths greater than 50 GHz with high-impedance probe head High-impedance, turnkey solution delivers bandwidths up to 52 GHz Brickwall and 40 GHz ...

Tektronix has introduced a 20 GHz differential scope probe. It costs $16,900. It is worth every penny. The P7520 was an extension of the 8 GHz P7380, but still required a huge multi-year and ...

Passive, high-impedance probes use voltage dividers in which each element is an R-C network rather than just a resistor. When the time constants of the two networks are equal, the circuit ...

A differential probe, a device for measuring the voltage between two points in a circuit rather than the voltage between a point and ground, it an extremely useful addition to any electronics bench.
